POWER GENERATION CELL AND METHOD FOR MANUFACTURING POWER GENERATION CELL

To reduce the cost for forming a reaction gas flow path while maintaining power generation characteristics.SOLUTION: A power generation cell 12 of a fuel cell 16 includes an electrolyte membrane/electrode structure 30 in which electrodes 36 each having a conductive and porous gas diffusion layer 42 are arranged on both sides of an electrolyte membrane 34, metal separators 32 that sandwich the electrolyte membrane/electrode structure 30 therebetween, and a conductive flow path forming body 44 that is interposed between the gas diffusion layer 42 and the separators 32 to form a reaction gas flow path 58. At least portions of the separators 32 facing the flow path forming body 44 are flat. A first surface 48a of the flow path forming body 44 and a second surface 54 of the gas diffusion layer 42 which face each other are joined to each other by an adhesive layer 55 which is arranged in an island shape with respect to the first surface 48a and the second surface 54.SELECTED DRAWING: Figure 4 【課題】発電特性を維持しつつ、反応ガス流路を形成するためのコストを低減する。【解決手段】燃料電池１６の発電セル１２は、導電性且つ多孔質性のガス拡散層４２を有する電極３６が電解質膜３４の両側に配設された電解質膜・電極構造体３０と、電解質膜・電極構造体３０を挟む金属製のセパレータ３２と、ガス拡散層４２及びセパレータ３２の間に介在して反応ガス流路５８を形成する導電性の流路形成体４４とを備える。セパレータ３２の少なくとも流路形成体４４に臨む部分は平坦である。互いに対向する流路形成体４４の第１面４８ａとガス拡散層４２の第２面５４とは、第１面４８ａ及び第２面５４に対して島状に配置された接着剤層５５により接合されている。【選択図】図４
