Title:
FUEL CELL AND METHOD FOR ALIGNING ITS MEMBRANE-ELECTRODE ASSEMBLY
Document Type and Number:
WIPO Patent Application WO/2009/017208
Kind Code:
A1
Abstract:
Misalignment of an assembly (e.g., an MEGA) is effectively prevented while ensuring the strength of a conductive porous body. A fuel cell comprises a membrane-electrode assembly (11), an anode conductive porous body (24) provided on one side of the membrane-electrode assembly (11), a cathode conductive porous body (25) provided on the other side, and separators (12, 13) sandwiching the membrane-electrode assembly (11), the anode conductive porous body (24), and the cathode conductive porous body (25). A recessed portion (25d) is formed in one of the anode conductive porous body (24) and the cathode conductive porous body (25). At least a part of the membrane-electrode assembly (11) is accommodated in the recessed portion (25d). It is preferable that at least a part of the portion other than the recessed portion (25d) of the conductive porous body (25) is pressed and crushed.
