Abstract

A second end plate constituting a fuel cell stack is provided with a cooling medium supply manifold member and a cooling medium discharge manifold member. The second end plate is also provided with a mount member that affixes the fuel cell stack to an automobile body frame and covers the cooling medium discharge manifold member.

First claim

The invention claimed is:

1. A fuel cell stack comprising a plurality of fuel cells for generating electrically energy by electrochemical reactions of a fuel gas and an oxygen-containing gas, the fuel cells being stacked together in a stacking direction, end plates being provided at both ends of the fuel cells in the stacking direction, at least one of the end plates having a fluid manifold member configured to allow a coolant, a fuel gas, or an oxygen-containing gas as fluid to flow through the fuel cells,
wherein the fluid manifold member is connected to a pair of fluid passages configured to allow the fluid to flow through the fuel cells of a single fuel cell stack in the stacking direction;
the fuel cell stack further comprises a mount member attached to the one of the end plates;
the mount member is configured to cover the fluid manifold member, and fix the fuel cell stack to an installation position; and
the mount member is configured to cover the fluid manifold member at a position where the fluid manifold is connected to the end plate.

2. The fuel cell stack according to claim 1 , wherein the fluid manifold member is a coolant manifold member configured to allow the coolant as the fluid to flow through the fuel cells.

3. The fuel cell stack according to claim 2 , wherein the coolant manifold member includes a coolant supply manifold member configured to supply the coolant and a coolant discharge manifold member configured to discharge the coolant;
wherein the mount member is configured to cover both of the coolant supply manifold member and the coolant discharge manifold member together.
