Fuel Cell Systems The requirements for fuels for fuel cell systems are still evolving as improvements in catalysts designed for fuel cell systems continue. Catalyst poisons, such as sulfur and amines, can be dealt with on-board the vehicle, however; this adds complexity to the fuel processor and may impact overall efficiency due to added vehicle weight. Requirements for water self-sufficiency and high reforming efficiencies may also limit the [...]
