Fuel cell module and fuel cell

Abstract

For the purpose of providing a fuel cell module having a small number of molding processes and favorable productivity, the edge of a polymer electrolyte membrane ( 44 ) exposed at the outer periphery of an electrode section, which is formed by providing an anode electrode ( 46 a ) and a cathode electrode ( 46 b ) on the polymer electrolyte membrane ( 44 ), is placed on the upper surface of one frame ( 47 a ); and another frame ( 47 c ) is molded on the upper surface of the one frame ( 47 a ) by injecting a resin material having a smaller Young's modulus than the one frame ( 47 a ), and a seal section ( 49 ) made from the same material as the other frame ( 47 c ) is simultaneously molded on the lower surface of the other frame ( 47 a ).

1 . A fuel cell module in which an edge of a polymer electrolyte membrane is supported by a frame body, wherein
 the frame body is made up of one frame and another frame joined so as to sandwich the edge of the polymer electrolyte membrane therebetween; and   the other frame is formed of a resin material having a smaller Young's modulus than the one frame and a seal section is formed on the surfaces of both frames opposite to a joint surface of the one frame with the other frame.   
     
     
         2 . The fuel cell module according to  claim 1 , wherein an aperture from which is exposed the polymer electrolyte membrane is formed in the other frame. 
     
     
         3 . A fuel cell that is a stack with a layered structure including the plurality of fuel cell modules according to  claim 1  connected in series, wherein the stack is arranged so that a fuel gas and an oxidant gas are supplied to an anode electrode and a cathode electrode of each fuel cell module.
