摘要： PROBLEM TO BE SOLVED: To provide a fuel cell capable of obtaining high generating performance. SOLUTION: The fuel cell 10 includes a membrane-electrode assembly 20, current collectors 30, 40 fixed to the electrode surfaces of the membrane-electrode assembly and having conductivity and gas permeability, separators 50, 60 arranged on the opposite sides to the membrane-electrode assembly of the current collectors and partitioning spaces 51, 61 for reaction gas flow between the current collectors and themselves. In the fuel cell, the current collector is fixed to the catalyst layer, so that high efficiency of current collection can be obtained without applying the additional fastening load to the fuel cell. The space for reaction gas flow is formed with the separator and the current collector, thereby installation of a gas diffusion layer and a gas passage member is made unnecessary. Gas diffusion resistance to the catalyst layer of the reaction gas is made low, and exhaust resistance of produced water from the catalyst layer is made low. Accordingly, power generation performance is increased. COPYRIGHT: (C)2010,JPO&INPIT
