What You'll Learn
The benefits of hydrogen as a fuel source
Hydrogen is a clean and efficient alternative to conventional power sources. It is a zero-emission fuel source, producing only water and heat when consumed in a fuel cell. This is in stark contrast to the harmful pollutants emitted by fossil fuels, which contribute significantly to global greenhouse gas emissions and air pollution. Hydrogen fuel cells also virtually eliminate nitrogen oxides (NOx) and sulfur oxides (SOx), improving air quality and creating a healthier environment.
Hydrogen is a versatile fuel source that can be produced from a variety of domestic resources, including natural gas, coal, nuclear power, biomass, and renewable power like solar and wind energy. This makes it an attractive option for transportation and electricity generation applications, as it can be used in cars, houses, and portable power solutions. Hydrogen can also be used in industrial applications such as refining petroleum, treating metals, producing fertilizer and other chemicals, and processing foods.
One of the key advantages of hydrogen fuel cells is their high efficiency. They can directly convert chemical energy into electrical energy, bypassing the losses associated with combustion. This results in a greater energy output from the same amount of fuel. Hydrogen fuel cells in a combined heat and power system can achieve efficiencies greater than 60%, compared to around 25% for internal combustion engines and 35% for power plants.
Additionally, hydrogen fuel cells offer notable operational durability and reliability. Some designs have demonstrated lifespans exceeding 20,000 hours, and unlike batteries, hydrogen stored as a gas or liquid remains ready for use, ensuring a dependable energy source. Hydrogen fuel cells also require minimal maintenance, positioning them as a sustainable solution for long-term energy needs.
Furthermore, hydrogen can be transported through existing gas pipelines, reducing the need for expensive new infrastructure. Hydrogen can also be stored as a gas in large volumes in natural geological formations or in smaller volumes in pressurized stationary or portable tanks. This makes it a viable option for road, air, and shipping transportation, with companies like DHL already utilizing hydrogen-powered vehicles.

How to split water into oxygen and hydrogen
The process of splitting water into oxygen and hydrogen is called water splitting or electrolysis. It involves passing an electric current through water to separate its components. Here is a step-by-step guide on how to split water into oxygen and hydrogen:
Firstly, gather the required materials. You will need a medium-sized clear container to hold the water, two wires, a battery, and two electrodes (preferably platinum). You may also need rubber gloves and safety goggles for protection.
Now, fill the container with water. Ensure that the water level is sufficient to submerge the electrodes. Next, connect one end of each wire to the battery and the other end to an electrode. Carefully place the electrodes into the water, ensuring they are not touching each other. The electrodes should be fully submerged.
At this point, you can proceed with caution. Turn on the power source, and you will begin to see bubbles forming around the electrodes. The bubbles around the negative electrode (cathode) will be hydrogen, and those around the positive electrode (anode) will be oxygen. You can collect these gases in separate containers for further use or experimentation.
This process of water electrolysis is a fundamental concept in understanding the operation of fuel cells, including those in the Fuel Cell Car Science Kit. The kit includes a reversible PEM (polymer electrolyte membrane) fuel cell, which combines the functions of an electrolyzer and a fuel cell. When electricity is applied, the device acts as an electrolyzer, splitting water into oxygen and hydrogen. The hydrogen produced can then be used to power the fuel cell car.
By understanding how to split water into oxygen and hydrogen, you can explore the potential of hydrogen as a clean and sustainable energy source for the future of transportation.

Using hydrogen to generate electricity
The Horizon Fuel Cell Car Science Kit is a great tool for teaching students about the principles of fuel cell vehicles and renewable energy sources. The kit includes everything needed to generate electricity using hydrogen, including a reversible PEM fuel cell, a solar panel, and an experiment guide.
The first step in using hydrogen to generate electricity is to split water into oxygen and hydrogen through a process called electrolysis. This can be done using the solar panel included in the kit to power the electrolysis reaction. The PEM fuel cell then combines the functions of an electrolyzer and a fuel cell, acting as an electrolyzer when an electrical current is applied.
Next, the hydrogen produced in the electrolysis reaction is used to power the fuel cell, generating electricity. This electricity can be used to power an electrical circuit or motor, such as the one included in the Horizon kit, which can drive a small car. The car can also be equipped with an LED light, a reversible polymer electrolyte membrane (PEM) fuel cell, and a power supply battery pack.
By using hydrogen to generate electricity, the kit demonstrates a clean and sustainable energy source that has the potential to reduce CO2 emissions from transportation. Hydrogen is the most common element in the universe and, as a clean fuel, has the ability to replace fossil fuels, thus reducing greenhouse gas emissions. The Horizon kit also allows students to explore other renewable energy sources, such as solar and wind power, and investigate chemistry and physics concepts related to renewable energy.

How to design and build an H2-powered car
Hydrogen fuel cell vehicles (HFCVs) are powered by a fuel cell stack that uses pure hydrogen (H2) to generate electricity and propel the car forward. HFCVs are similar to electric cars but are powered by hydrogen instead of large, heavy batteries. Hydrogen is a promising alternative fuel that has the potential to replace fossil fuels and significantly reduce CO2 emissions.
To design and build an H2-powered car, you will need to understand the basic principles of HFCVs and the technology involved. Start by familiarizing yourself with the science behind electrolysis and how it can be used to split water into oxygen and hydrogen. This process involves using an electrical current to break down water (H2O) into its constituent elements, hydrogen (H2) and oxygen (O2). The hydrogen produced can then be used to power the vehicle.
The Horizon Fuel Cell Car Science Kit is a great tool to learn about the principles of HFCVs. It includes a reversible PEM (polymer electrolyte membrane) fuel cell that can split water into hydrogen and oxygen, and a solar panel to power the electrolysis process. The kit also comes with a motorized chassis, an LED light, a motor, cylinders for water and hydrogen gas, and other necessary parts. With this kit, you can build your own H2-powered car and experiment with different technologies to explore renewable energy sources.
When designing your H2-powered car, consider the following:
- The source of hydrogen: Pure hydrogen needs to be generated through electrolysis or derived from fossil fuels like natural gas.
- Storage: Hydrogen needs to be stored in carbon-fiber-reinforced fuel tanks to ensure safety and meet regulations.
- Fuel cell stack: This is where the hydrogen combines with oxygen to produce electricity and propel the car.
- Motors: Electric motors powered by the fuel cell stack turn the wheels of the car.
- Safety: Ensure your design includes safety features such as hydrogen sensors and automatic valve closure in case of a leak or collision.
Building an H2-powered car can be a complex process, but with the right tools, knowledge, and experimentation, you can gain valuable insights into the potential of hydrogen as a clean and sustainable energy source for the future of transportation.

The principles of real-scale fuel cell vehicles
Fuel cell vehicles (FCVs) are electric vehicles that use fuel cells, often in conjunction with a small battery or supercapacitor, to power their onboard electric motors. They are considered to be more environmentally friendly than traditional vehicles as they generate electricity from oxygen and compressed hydrogen, rather than burning fossil fuels.
FCVs have been in development since the 1970s, with General Electric conducting research on PEM fuel cells. By the 1990s, automobile manufacturers began to show interest in fuel cell applications, and in 2001, the first 700 Bar (10000 PSI) hydrogen tanks were demonstrated, reducing the size of the fuel tanks and extending the range of potential FCVs.
In 2002, the first government-certified commercial FCVs, the Toyota FCHV and Honda FCX, were introduced, and in 2008, Honda established the world's first FCV dealer network, leasing hydrogen FCVs to private customers. In 2013, Hyundai Motors began production of the Hyundai ix35 FCEV, which was the first mass-produced FCV, and in 2014, Toyota began selling the first dedicated FCV, the Toyota Mirai.
Despite these advancements, there are still challenges and criticisms surrounding FCVs. As of 2020, there was limited hydrogen infrastructure, with fewer than 50 hydrogen fuelling stations publicly available in the US. This lack of infrastructure, coupled with high fuel costs and the potential for greenhouse gas emissions during hydrogen production and transportation, has led to doubts about the efficiency and cost-effectiveness of FCVs compared to other zero-emission technologies.
However, research and development (R&D) efforts continue worldwide, with a focus on reducing fuel cell technology costs, improving performance, and addressing the challenges associated with hydrogen infrastructure. Government-industry programs on FCV deployment and hydrogen infrastructure development are more prominent in Asia and Europe, particularly in Japan and Germany. The U.S. Department of Energy (DOE) has also launched the "H2@Scale" initiative to tackle hydrogen infrastructure issues.
