摘要： A polymer electrolyte fuel cell comprising a first separators for oxidizing gas and a second separator for fuel gas and a membrane/electrode assembly sandwiched between the separators. A first group of oxidizing gas flow passages flowing, from an entrance towards a turning point, has the longer length than a second group of oxidizing gas flow passages. The second group of flow passages, from the turning point towards an exit, are formed on the plane of the first separator. A downstream of the flow passages of the first group is located near an upper stream of the flow passages of the second. The flow passages of the first group and flow passages of the second group adjoin one another on the plane of the first separator.

摘要： A polymer electrolyte fuel cell comprises a fuel cell stack and a humidifier. The fuel cell stack includes plural cells in which each cell has a pair of electrodes and a proton-conductive electrolyte membrane arranged between the pair of electrodes, wherein an oxidant gas or a fuel gas passes through the humidifier before being fed to the fuel cell stack, and wherein a wet gas containing water or water vapor also passes through the humidifier. In the fuel cell, the humidifier includes a porous separating layer and a hydrophilic water-releasing layer, wherein the separating layer is configured to separate the wet gas from the oxidant gas or the fuel gas in the humidifier, and wherein the hydrophilic water-releasing layer is disposed in a side of the oxidant gas or the fuel gas to the separating layer in the humidifier.
