These maintenance activities can represent about 22% of the whole stack system cost for each repair or maintenance instance.
The cost of maintenance for a fuel cell stack can vary depending on various factors. Firstly, the operating conditions can impact the maintenance costs. For example, high temperatures or high humidity can shorten the lifespan of the fuel cell by causing the inner components to wear out more quickly, leading to increased maintenance and replacement costs.
Secondly, the availability and price of hydrogen fuel can affect maintenance costs. Hydrogen fuel availability and pricing vary across regions, with some areas having better infrastructure and lower hydrogen prices than others. The ease of accessing hydrogen fuel can impact the overall maintenance costs of a fuel cell stack.
Additionally, the longevity of the fuel cell stack and the long-term savings associated with its use should be considered. Fuel cell stacks have a long lifespan, and with proper maintenance, they can last up to 10 to 20 years. The high efficiency of fuel cell stacks compared to fossil fuel-based systems means that they consume less fuel to generate the same amount of power, resulting in lower costs in the long run.
Moreover, advancements in fuel cell technology have led to reduced maintenance requirements and increased lifespan of fuel cell systems, making them more cost-effective to buy and operate. The increased competition in the market and government incentives have also contributed to driving down the costs of fuel cell stacks.
Overall, while maintenance costs are an important consideration, the long-term savings, increased efficiency, and lower maintenance requirements compared to traditional fossil fuel systems make fuel cell stacks a more attractive and cost-effective option.

Hydrogen fuel costs
The cost of hydrogen fuel is a critical factor in determining the overall expense of operating a fuel cell stack. Hydrogen fuel costs can vary significantly depending on various factors, including regional availability, infrastructure, and accessibility.
For instance, California boasts an extensive hydrogen infrastructure, making it relatively affordable for consumers in that state. In contrast, other regions may face challenges in obtaining hydrogen fuel, resulting in higher prices. Therefore, the operating environment can significantly influence the overall costs associated with a fuel cell stack.
The price of hydrogen fuel is also subject to fluctuations over time. In recent years, the cost of fuel cell stacks has witnessed a significant decline. For example, the average price of a 120kW fuel cell stack stood at approximately $1 million in 2010, but by 2022, it had dropped to around $200,000. This decrease in cost is attributed to several factors, including increased competition among manufacturers, innovations in production techniques, and government incentives promoting the development of hydrogen fuel cells and electrolyzers.
Looking ahead, the cost of hydrogen fuel cells is expected to continue its downward trend. With advancements in technology and growing demand, prices are projected to fall below $100,000 in the coming decade.
When considering the cost of hydrogen fuel, it is essential to evaluate the overall lifecycle expenses of a fuel cell stack. This includes not only the initial purchase price but also maintenance costs, operating conditions, and potential long-term savings. By taking into account these factors, consumers can make informed decisions about the true cost of investing in a fuel cell stack system.

Operating conditions
The cost of a fuel cell stack is influenced by a range of factors beyond the initial purchase price, such as operating conditions, maintenance costs, and fuel prices. Optimizing the operating conditions of a fuel cell stack is crucial to ensure its efficient performance and longevity. Here are some key considerations for operating a fuel cell stack:
Temperature Control: Cell temperature is a critical factor in a fuel cell stack's operation. Elevated temperatures improve reaction kinetics, but they also pose challenges in maintaining proton conductivity membrane hydration. At extremely high temperatures, the inner components of the fuel cell can wear out faster, shortening its lifespan. Therefore, the optimal temperature range for fuel cell stacks is typically around 80°C, which provides a balance between adequate kinetics and membrane hydration.
Gas Flow Rate: Controlling the flow rate of hydrogen and reactant gases is essential to prevent hydrogen starvation, which can lead to irreparable damage due to carbon corrosion. Before connecting the stack to a load, circulating hydrogen through the stack ensures that the hydrogen channel is filled. Faraday's law can be applied to determine the appropriate flow rate.
Humidity Management: Humidity is another important parameter in fuel cell stack operation. While external humidifiers can be used to control humidity, some fuel cell stacks, such as PEM fuel cells, are self-humidified. Humidity influences cell hydration, and optimizing it requires understanding the water balance within the cell.
Pressure Control: Along with humidity and gas flow rate, pressure is a factor that requires management. In some cases, such as small stacks, pressure gradients may be utilized to control the anode flow by manipulating the purge cycle, which involves opening and closing the exhaust valve to introduce fresh hydrogen.
Performance Measurement: To ensure optimal operation, it is important to measure the performance of a fuel cell stack. This is typically done by analyzing its polarization curve, which relates stack voltage (V) to current (A). Additionally, a stack power curve can be obtained by multiplying cell voltage by the current, providing information about stack power (W) relative to stack current.

Resale value
When considering the cost of a fuel cell stack, it is important to look at the 'true' cost, which takes into account the entire life cycle of the system. One of the most significant factors is the initial purchase price, which can range from as little as $79 for a PEM Reversable Fuel Cell to $2500 to $2900 for an H-500 fuel cell stack, all the way up to $180,000 to $220,000 for a 120kW Liquid Cooled VL-Series fuel cell stack. However, it is important to remember that fuel cells have a long lifespan, and with proper maintenance, they can last up to 10 to 20 years.
The resale value of a fuel cell stack is an important factor in determining the overall cost of ownership. Fuel cells have longer lifespans than traditional fossil fuel engines, which can significantly affect their resale value. By subtracting the resale value from the initial purchase price, you can get a better idea of the total cost of ownership over the entire lifecycle of the system.
Maintenance costs are another factor that can impact the resale value of a fuel cell stack. Regular inspections, replacement of worn-out parts, and monitoring of the stack's internal systems are necessary to ensure the system lasts a long time. These costs can add up over time, but they are generally lower than the costs of maintaining traditional fossil fuel-based systems due to fuel cells having fewer moving parts. Proper maintenance can help extend the lifespan of the fuel cell stack, potentially increasing its resale value.
Efficiency is also a key factor in determining the resale value of a fuel cell stack. Fuel cells have a higher efficiency rate than fossil fuel-based systems, with hydrogen fuel cell stacks achieving efficiencies of up to 61% or higher. Increased efficiency means less fuel is consumed to generate the same amount of power, resulting in lower operating costs over time. This can make fuel cell stacks more desirable and potentially increase their resale value.
Additionally, the operating environment can affect the resale value of a fuel cell stack. Very high temperatures or high humidity can shorten the fuel cell's lifespan by causing the inner components to wear out quickly. Therefore, it is important to consider the intended operating conditions when purchasing a fuel cell stack, as this can impact its longevity and, consequently, its resale value.
Overall, while the initial purchase price of a fuel cell stack may seem high, the combination of a long lifespan, low maintenance costs, high efficiency, and potential for a favourable operating environment can result in a significant resale value. This helps to lower the overall cost of ownership and makes fuel cell stacks a more attractive investment.
