電気化学反応セルスタック
Document Type and Number:
Japanese Patent JP7249981
Kind Code:
B2
Abstract:
To suppress a concentration of a stress to a connection part between a gas passage member and an end member.SOLUTION: An electrochemical reaction cell stack comprises: an electric and chemical reaction block, structured by a plurality of electric-chemical reaction units arranged in parallel to a first direction; an end member that is arranged in one side of the first direction to the electric-chemical reaction block, and in which an end penetration hole is formed; and a cylinder gas passage member that is arranged on one side of the first direction to the end member. The gas passage member is connected to the end member, in which a gas penetration hole communicated with the end penetration hole is formed. The electrochemical reaction cell stack is communicated with a gas chamber which faces to a specific electrode which is one of a fuel electrode and an air electrode, in which a manifold containing the end penetration hole is formed. The electrochemical reaction cell stack is fixed to the end member, and comprises a reinforcement member that contacts to a part separated from the end member in the first direction of an outer peripheral surface of the gas passage member.SELECTED DRAWING: Figure 2
