FUEL CELL STACK

摘要

A fuel cell stack includes a stack body formed by stacking a plurality of fuel cells together in a stacking direction. A second end plate is provided at one end of the stack body in the stacking direction. A pair of coolant supply passages are provided at upper and lower positions of the second end plate for allowing a coolant to flow into the fuel cells. A coolant supply manifold member is attached to the second end plate, and an insulating plate is provided between the second end plate and the coolant supply manifold member.

1. A fuel cell stack including a stack body formed by stacking a plurality of fuel cells together in a stacking direction for generating electrical energy by electrochemical reactions of a fuel gas and an oxygen-containing gas, a fluid passage extending through the stack body in the stacking direction for allowing a fluid, which is a coolant, the fuel gas, or the oxygen-containing gas, to flow through the fuel cells, the fuel cell stack further including end plates provided at both ends of the stack body in the stacking direction, at least one of the end plates having a fluid manifold member connected to the fluid passage,
wherein an insulating plate is provided between the one of the end plates and an attachment surface of the fluid manifold member.
