What You'll Learn
Using a PEM fuel cell to produce hydrogen gas
To make a hydrogen fuel cell toy car, you'll first need to understand how to use a PEM fuel cell to produce hydrogen gas. Here's a detailed guide:
Proton Exchange Membrane (PEM) fuel cells are a leading candidate for powering automobiles with hydrogen gas, as they can operate at low temperatures and quickly vary their output to meet shifting power demands. PEM fuel cells are built out of membrane electrode assemblies (MEA), which include electrodes, an electrolyte, a catalyst, and gas diffusion layers.
The key to the PEM fuel cell's operation is the proton exchange membrane, a thin, porous polymer membrane that allows the passage of protons while blocking electrons. This membrane is located between the anode and cathode catalysts. The overall chemical reaction in a PEM fuel cell can be represented as: Hydrogen + Oxygen → Water + Electricity.
To produce hydrogen gas using a PEM fuel cell, you would typically start by connecting the fuel cell stack to the necessary electrical and gas supply lines, including hydrogen and oxygen (air) feeds. The catalyst in the PEM fuel cell separates hydrogen atoms into protons and electrons, which then take different paths to the cathode. The electrons flow through an external circuit, creating electricity, while the protons migrate through the electrolyte to the cathode.
It's important to note that a PEM hydrogen fuel cell requires high-purity hydrogen gas to function effectively. Impurities in the hydrogen gas can lead to reduced efficiency and degradation. Proper water management is also crucial to maintaining the efficiency of the PEM fuel cell, as it produces water as a byproduct.
PEM fuel cells offer a promising alternative to traditional hydrocarbon fuels, and their ability to quickly adjust output makes them ideal for powering automobiles, including toy cars.

Powering an electric motor and gearbox
To power an electric motor and gearbox using a hydrogen fuel cell, you can follow the below steps. Firstly, you will need to generate hydrogen gas by adding distilled water to the onboard tank and connecting a solar cell or battery pack to initiate the electrolysis process. This will produce hydrogen gas, which can then be combined with oxygen in a fuel cell to generate electricity. This electricity can then be used to power the electric motor and gearbox.
The electric motor and gearbox can be powered using a PEM (Proton Exchange Membrane) fuel cell, which is a combination of an electrolyser and a fuel cell. This setup allows for the production of hydrogen gas and its subsequent conversion into electricity. The electricity produced can then be used to power the electric motor, with the gearbox providing the necessary mechanical advantage to lift a weight or perform other mechanical tasks.
The voltage from the fuel cell will initially be a little over two volts, but it will quickly decline as the hydrogen and oxygen bubbles are used up in the reaction. Despite this, the electric motor and gearbox can still be effectively powered by the fuel cell, and any excess electricity can be stored for later use.
By using this setup, students can investigate the process of converting electrical energy into mechanical energy and determine the amount of work produced by the motor. This activity provides a practical application of the core concepts of forces, Newton's laws of motion, green design, and energy transformations in the context of designing and building toy cars.

Exploring renewable fuels and green materials
Hydrogen fuel is a clean energy source that can be used in cars, homes, and portable power applications. Hydrogen fuel cells produce electricity by combining hydrogen with oxygen, resulting in water as the only byproduct. This makes hydrogen an attractive option for transportation, as it is a zero-emissions fuel. Hydrogen can be produced from a range of resources, including natural gas, renewable liquid fuels, and electricity generated from wind, solar, geothermal, or biomass.
To explore renewable fuels and green materials in the context of a hydrogen fuel cell toy car, we can look at both the energy source and the construction materials used. Hydrogen, as a renewable fuel, is an excellent choice for powering toy cars. With the help of a solar cell or battery pack, distilled water can undergo electrolysis to produce hydrogen gas. This gas is then combined with oxygen in a fuel cell to generate electricity and power the car. Such a kit can serve as an educational tool, providing hands-on experience with renewable energy and fuel cell technology.
When it comes to the construction of toy cars, several green materials can be employed to enhance sustainability. One popular option is recycled plastic, which helps reduce waste and prevent plastic pollution in landfills and oceans. Recycled plastic can be derived from various sources, such as plastic bottles, milk jugs, and cardboard, and it offers durability comparable to that of virgin plastic. Additionally, bamboo is a renewable and lightweight alternative that requires fewer pesticides and less water than traditional wood, making it well-suited for toy car manufacturing.
Another sustainable option for toy cars is bio-based plastics, also known as bioplastics. These materials are derived from renewable resources like corn starch, vegetable fats and oils, sugarcane, or cassava. Bioplastics have a smaller carbon footprint than conventional plastics and are biodegradable, naturally decomposing over time. By choosing bioplastics, we can reduce our environmental impact and contribute to a healthier planet for future generations.
By combining renewable fuels like hydrogen with green materials in toy car manufacturing, we can create sustainable and environmentally friendly products. This dual approach not only educates children about renewable energy but also fosters a mindset that prioritizes sustainability and eco-consciousness from an early age.

Understanding the principles of renewable energy
Renewable energy is energy that is collected from renewable sources that are naturally replenished, such as sunlight, wind, rain, tides, waves, and geothermal heat. Renewable energy sources are an important alternative to non-renewable sources, such as fossil fuels, which are limited in supply and contribute to climate change through carbon dioxide emissions and other pollutants.
One example of a renewable energy source is hydrogen, which can be used as a clean fuel for vehicles, in chemical production, and as an energy storage medium. Hydrogen fuel cells work by passing hydrogen through an anode, where it is separated into electrons and protons. The electrons then flow through an external circuit, creating a flow of electricity, while the protons move through a membrane to the cathode. At the cathode, the electrons, protons, and oxygen from the air combine to form water.
Hydrogen fuel cells are a promising technology for the future of transportation as they can reduce greenhouse gas emissions and air pollutants. They also have the ability to replace all the fossil fuels used on the road today, offering a more sustainable energy system. Hydrogen fuel cells can also be used in conjunction with solar panels or wind turbines to generate electricity, as seen in some educational toy car kits.
These kits provide a comprehensive introduction to the principles of renewable energy and microgrids. They allow users to generate hydrogen through water electrolysis and convert it into electricity using a PEM fuel cell, demonstrating the potential for hydrogen to be used as a clean and efficient energy source. By building and experimenting with these kits, students can gain a deeper understanding of renewable energy sources, the chemistry and physics concepts behind them, and their potential applications in the real world.
