Title:
FUEL CELL STACK
Document Type and Number:
Japanese Patent JP2011192552
Kind Code:
A
Abstract:

To provide a fuel cell stack capable of reducing heat radiation and thermal stress in a simple and compact structure and improving in assembling properties.

A fuel cell 30 has a separator 40, and the separator 40 integrally includes a fuel gas supply section 48 for forming a fuel gas supply communication hole 46 at a central portion, a bridge section 50 wherein a fuel gas supply passage 58 is formed, and a holding section 52. A laminated body 95 formed by laminating a plurality of fuel cells 30 is constituted, and side section insulating members 114a, 114b being parallel with an extension line of the bridge section 50 and along both outer edge sections 52a, 52b of the holding section 52 and being parallel with an extension line of the bridge section 50 are arranged on the laminated body 95. The side section insulating members 114a, 114b restrain heat radiation from the plurality of fuel cells 30, and form a positioning standard at the time of laminating of the fuel cells 30.
