Beschreibung
Zusammenfassung:	A fuel cell includes: a membrane electrode assembly (10) in which electrodes (14 and 16) are disposed on both sides of the electrolyte membrane (12); a gas diffusion layer (17) laminated on one side of the membrane electrode assembly (10); a resin frame (20) spaced apart from an outer periphery of the gas diffusion layer (17) and bonded to one side of the membrane electrode assembly (10) so as to surround the outer periphery of the gas diffusion layer (17); and a resin sheet (60) disposed to fill a gap between the inner periphery of the resin frame (20) and the outer periphery of the gas diffusion layer (17) between the gas diffusion layer (17), the resin frame (20), and the membrane electrode assembly (10). 연료 전지는, 전해질막(12)의 양면에 전극(14, 16)이 배치된 막 전극 접합체(10)와, 상기 막 전극 접합체(10)에 있어서의 한쪽 면 상에 적층된 가스 확산층(17)과, 상기 가스 확산층(17)의 외주로부터 이격되어, 상기 가스 확산층(17)의 외주를 둘러싸도록, 상기 막 전극 접합체(10)의 한쪽 면 상에 접합된 수지 프레임(20)과, 상기 가스 확산층(17) 및 상기 수지 프레임(20)과, 상기 막 전극 접합체(10) 사이에 있어서, 상기 수지 프레임(20)의 내주와 상기 가스 확산층(17)의 외주 사이를 메우도록 배치된 수지 시트(60)를 구비한다.
