Fuel cell equipped with polymeric electrolyte film, has gas transfer route through which reactive gas flows, whose volume is decreased along flow direction as result of reduction of cross-section of route from inlet to exit

摘要

The fuel cell has a cathode inlet (1) from which the reactive gas flows to cathode exit (2) through gas transfer route (3). The volume of route through which reactive gas flows, is decreased along the flow direction as a result of reduction of cross-section of route from inlet to exit.
