Problems solved by technology

[0004] However, the end side of the laminated body in the stacking direction (hereinafter also simply referred to as the end side) is easier to dissipate on the end side than the central side in the stacking direction of the laminated body because heat radiation through the terminal block or the like is promoted. become cryogenic
When the end side of the stack becomes cold and dew condensation occurs due to the influence of external air temperature, etc., the diffusivity of fuel gas and oxidant gas (reactive gas) may decrease, and the power generation stability of the fuel cell stack may decrease.

Abstract

Fuel cell stack and method of producing dummy cell. A fuel cell stack at least includes a stack body including a plurality of power generation cells each having a membrane electrode assembly stacked in a stacking direction, and a first dummy cell provided at one end of the stack body in the stacking direction. A dummy structural body of the first dummy cell is joined to a dummy resin frame memberthrough an adhesive layer which adheres a first outer peripheral portion and a second outer peripheral portion, and inner periphery of the dummy resin frame member to each other.

Description

technical field [0001] The present invention relates to a fuel cell stack including a stack in which a plurality of power generating cells are stacked, and a dummy cell arranged at at least one end in the stacking direction of the stack, and a method for manufacturing the dummy cell. It has an electrolyte membrane-electrode structure and a resin frame member surrounding the outer periphery of the electrolyte membrane-electrode structure. Background technique [0002] In general, a solid polymer fuel cell employs a solid polymer electrolyte membrane (hereinafter also simply referred to as an electrolyte membrane) formed of a polymer ion exchange membrane. A fuel cell includes an electrolyte membrane-electrode structure (MEA) in which an anode electrode is arranged on one surface of an electrolyte membrane and a cathode electrode is arranged on the other surface. [0003] The electrolyte membrane-electrode structure is sandwiched between separators to form a power generating ...
