In order to obtain an electrolyte membrane-electrode assembly using a thin electrolyte membrane, the present invention provides a production method of an electrolyte membrane-electrode assembly comprising: a step of forming a hydrogen ion-conductive polyme...

A fuel cell provides a high output at a high current density. The fuel cell has an anode electrode (24) and a cathode electrode (26) comprising a gas diffusion layer (6a, 6b), a water-repellent layer (30a, 30b) disposed on the gas diffusion layer (6a, 6b) ...

Fuel cell (1) comprises two electrodes (2) and an ion exchange membrane (6). The electrodes each have an electro-catalytic layer (4) and a gas feed for a reaction gas (7). The electro-catalytic layers each contain a standard catalyst. The fuel cell further...

Disclosed are a carbon porous membranous structure having fine interconnecting pores an average diameter of which is 0.05 to 10 µm and a porosity of 15 to 85% and a metal-dispersed carbon structure comprising that carbon porous membranous structure having...

A polymer electrolyte fuel cell (10) includes an electrode (17, 14) including a catalyst layer (15, 12) and a diffusion layer (16, 13). The catalyst layer (15, 12) is divided into a plurality of portions including an upstream portion and a downstream porti...
