Title:
SOLID POLYMER TYPE FUEL CELL
Document Type and Number:
WIPO Patent Application WO/2002/082572
Kind Code:
A1
Abstract:
A solid polymer type fuel cell which comprises: a pair of electrodes (2) and (3) having a catalyst layer (5) comprising catalyst particles which comprise a catalyst support and a catalyst deposited thereon and have been united with one another with an ion-conductive polymer binder; and a polymer electrolyte film (1) sandwiched between the electrodes (2) and (3) on their sides having the catalyst layer (5). The polymer electrolyte film (1) has a coefficient of dynamic viscoelasticity at 110°C of 1x10?9� to 1x10?11� Pa, and the ion-conductive polymer binder used for forming the catalyst layer (5) has a lower coefficient of dynamic viscoelasticity at 110°C than the polymer electrolyte film (1). The fuel cell further has, interposed between the polymer electrolyte film (1) and the catalyst layer (5) of each of the electrodes (2) and (3), a cushioning layer (6) comprising an ion-conductive material having a coefficient of dynamic viscoelasticity at 110°C which is lower than that of the polymer electrolyte film (1) and higher than that of the ion-conductive polymer binder in the catalyst layer (5).
