Abstract: The fuel cell with excellent power generation performance and high reliability and a manufacturing method of a fuel cell electrode by which the flooding phenomenon is hard to be caused at a contact portion with a separator because of small contact resistance with the separator. According to the manufacturing method of the fuel cell electrode, a first application process for applying an electrically conductive water repellent material including electrically conductive particles and water repellent particles on one side of a gas diffusion substrate having the gas permeability, a first sintering process for sintering the applied electrically conductive water repellent material, and a catalyst support process for supporting a catalyst on the other side of the gas diffusion substrate are provided.

Abstract: In order to improve gas permeability and electric conductivity, a solid polymer electrolyte fuel cell is so designed as to include an electrolyte 100 in the boom of an ion exchange membrane, a gas diffusion layer 110/120 arranged on each side of the electrolyte 100, and an electrode catalyst substance, dispersed in the gas diffusion layer 110/120.
