Title: FUEL CELL UNIT
Abstract:
A holder (16a) has air supply holes (HL1a, HL2a), and a plate material (14a) has through holes (PH1a, PH2a). The thermal expansion coefficient of the holder (16a) is higher than the thermal expansion coefficient of the plate material (14a). Air is supplied to a fuel cell stack (12) through the air supply hole (HL1a) and the through hole (PH1a), and a hydrogen gas is supplied to the fuel cell stack (12) through the air supply hole (HL2a) and the through hole (PH2a). The holder (16a) has recessed portions (CC1a, CC2a) having bottom surfaces in which the openings of the air supply holes (HL1a, HL2a) are formed. The plate material (14a) has projected portions having top surfaces in which the openings of the through holes (PH1a, PH2a) are formed, said projected portions being fitted into the recessed portions (CC1a, CC2a). A gas sealing material (18a) is filled into the space between the inner surface of the recessed portion (CC1a) and the outer surface of one projected portion.
