FUEL CELL AND FUEL CELL SYSTEM

摘要

A fuel cell is configured by sandwiching a membrane electrode assembly bonded respectively with an anode (411a) and a cathode (411c) on both sides of an electrolyte membrane (solid polymer membrane) between separators (42CA1, 42AN1). This fuel cell includes an anode side gas flow path (424d1, 424d2) for allowing the flow of a fuel gas in a first direction along the surface of the anode (411a), and a cathode side gas flow path (422d1, 422d2) for allowing the flow of oxidant gas along the surface of the cathode (411c) in a second direction opposite the first direction. A formed water capturing section (424d2, 422d2) for capturing at least one of formed water formed during generation of electricity contained in anode off gas and formed water contained in cathode off gas is provided in at least one of farthermost downstream in the direction of fuel gas flow in the anode side gas flow path (424d1, 424d2) and farthermost downstream in the direction of oxidant gas flow in the cathode side gas flow path (422d1, 422d2).
