PURPOSE:To prevent coagulation of an active catalyst on an electrode by forming a catalyst layer of a fuel cell electrode with a nonconductive inorganic compound carrier, a mixture of active catalyst and conductive particles, and a binder. CONSTITUTION:At least one of catalyst layers of a set of fuel cell electrodes is formed with nonconductive inorganic compound carrier having a conductivity of 10<-2>OMEGAcm (at room temperature), a mixture of active catalyst such as platinum and conductive particles such as carbon, and a binder such as polytetrafluoroethylene. A fuel cell using this catalyst layer prevents coagulation of catalyst particles and shows steady cell voltage over a lengthy period of time. |
