    • A cell according to the present invention is a fuel cell for generating an electric power by supplying one electrode with a fuel and the other electrode with an oxidant. In the fuel cell, a catalyst layer is formed on at least one surface of at least one of the one electrode and the other electrode. The catalyst layer is a layer including catalyst particles alone, a layer including a mixture of the catalyst particles and other particles, or a layer of a porous film carrying at least the catalyst particles, and a molecule including an ion-conducting functional group serving as an electrolyte is chemically bonded to a surface of at least one selected from the group consisting of the catalyst particles, the other particles and the porous film. At least one of the electrodes has a thin film electrolyte, a catalyst and an electron conducting substance, thereby suppressing the elution of the electrolyte from the catalyst layer in an electrode part and the accompanying voltage drop.
    • 根据本发明的电池是用于通过向一个电极供应燃料并且另一个电极具有氧化剂来产生电力的燃料电池。 在燃料电池中,在一个电极和另一个电极中的至少一个电极的至少一个表面上形成催化剂层。 催化剂层是仅包含催化剂颗粒的层,包含催化剂颗粒和其它颗粒的混合物的层或至少载有催化剂颗粒的多孔膜层,以及包含用作 电解质化学键合到选自催化剂颗粒,其它颗粒和多孔膜中的至少一种的表面。 电极中的至少一个具有薄膜电解质,催化剂和电子传导物质,从而抑制电解质从电极部分中的催化剂层的溶出以及伴随的电压降。
