摘要:
In a fuel cell power plant (9) air bleed is provided to the anode flow fields (13) of a stack (11) of fuel cells by introducing the air into the recycle loop (23, 24) upstream of the recycle drive (25). The source of air may be the cathode air supply device (31) that provides oxidant reactant gas to the cathode flow fields (14), or a separate, low pressure, low flow air pump (48) or a separate low pressure, low flow pump (45) connected from the cathode air supply devise (31) through flow controllers (41, 42) to the pressure side of the recycle loop (23, 24) at the exhaust of the anode flow fields (13).
