Abstract
Disclosed is a solid polymer electrolyte fuel cell which contains a catalyst impregnated layer in an ion exchange membrane which is electrically isolated but ion conductive. In place of the catalyst layer, catalyst particles existing in an anode and/or a cathode may be employed. The catalyst layer and the catalyst particles are attributable to the prevention of the lowering of a cell voltage and the employment of an inexpensive hydrocarbon ion exchange membrane and of a thin membrane.
