Title:
FUEL CELL SEALING STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2010/050339
Kind Code:
A1
Abstract:
Provided is a sealing structure using a gasket integrally formed with a separator arranged at both sides of an MEA in the thickness direction thereof via a GDL so as to sandwich the MEA. This structure can effectively prevent deformation of the MEA or shift of the GDL. A first GDL, a second GDL, and the separator are successively layered at both sides of the MEA in the thickness direction thereof. The gasket used for sandwiching the end portion of the MEA outside the first GDL and the second GDL is made from rubber or synthetic resin having rubber-like elasticity and integrally provided with the separators. The first GDL has an end portion which is formed so as to protrude from the external circumference of the second GDL and which can be positioned on the gasket. Formed also is a stepped support portion which can be supported at the same height as the support height of the second GDL.
