Fuel cells can be used for primary power, backup power, or combined heat and power (CHP) for stationary applications. Stationary fuel cells can be sized to power anything from a single-family home to a large business center, which means they make sense for a wide range of markets including retail, data centers, residential, telecommunications, and...
Fuel cells are not limited to pure hydrogen gas as fuel. Each type of fuel cell stack has different fuel tolerances. The lower the operating temperature of the stack, the stricter the requirements for pure fuel. For fuels other than pure hydrogen, an external fuel processing system may...
Most people wouldn’t think that much thought needs to be put into fuel cell components such as fuel cell gaskets, spacers, and end plates, however, every part of the fuel cell stack requires careful consideration. Incorrect fuel cell gaskets and end plates can lead to gas leaks and insufficient fuel cell stack...
In a previous blog post, we described bipolar plates and the associated materials for low-temperature fuel cells. The materials previously described are selected for fuel cell stacks at or slightly above room-temperature -- which means that the materials are chemically compatible with the stack between 0 – 140 °C. The fuel cells that operate at higher temperatures require...
