摘要： The present invention provides a solid polymer electrolyte fuel cell comprising a fuel cell stack formed by laminating a plurality of fuel cell units each of which includes a fuel electrode, an oxidant electrode, and a solid polymer electrolyte membrane interposed between the fuel and oxidant electrodes. The fuel cell unit is operable to generate an electric power through an electrochemical reaction between a first gas supplied to the side of the fuel electrode and a second gas supplied to the side of the oxidant electrode. In this fuel cell, the first gas supplied to the side of the fuel electrode and the second gas supplied to the side of the oxidant electrode are adapted to flow generally in opposite directions in the fuel cell stack, so that a water created on the side of oxidant electrode is reciprocally moved between the fuel electrode and the oxidant electrode to increase a water holding region in the solid polymer electrolyte membrane. The fuel cell of the present invention can improve fuel cell characteristics without providing any humidifier.
摘要翻译：本发明提供一种固体聚合物电解质燃料电池，其包括通过层叠多个燃料电池单元而形成的燃料电池堆，所述多个燃料电池单元包括燃料电极，氧化剂电极和插在燃料和氧化剂电极之间的固体聚合物电解质膜。燃料电池单元可操作以通过供应到燃料电极侧的第一气体和供给到氧化剂电极侧的第二气体之间的电化学反应产生电力。在该燃料电池中，供给到燃料电极侧的第一气体和供给到氧化剂电极侧的第二气体适于在燃料电池堆中大致相反地流动，从而在侧面产生水氧化剂电极在燃料电极和氧化剂电极之间往复移动，以增加固体聚合物电解质膜中的保水区域。本发明的燃料电池可以在不设置任何加湿器的情况下改善燃料电池特性。

摘要： The present invention provides a solid polymer electrolyte fuel cell comprising a fuel cell stack 21 formed by laminating a plurality of fuel cell units each of which includes a fuel electrode 23, an oxidant electrode 24, and a solid polymer electrolyte membrane 22 interposed between the fuel and oxidant electrodes. The fuel cell unit is operable to generate an electric power through an electrochemical reaction between a first gas supplied to the side of the fuel electrode 23 and a second gas supplied to the side of the oxidant electrode 24. In this fuel cell, the first gas supplied to the side of the fuel electrode 23 and the second gas supplied to the side of the oxidant electrode 24 are adapted to flow generally in opposite directions in the fuel cell stack 21, so that a water created on the side of oxidant electrode 24 is reciprocally moved between the fuel electrode 23 and the oxidant electrode 24 to increase a water holding region in the solid polymer electrolyte membrane 22.
