A passive fuel cell assembly including a membrane electrode assembly, an anode current collector, a cathode current collector, a hydrophilic and gas-impermeable layer, and a gas-liquid separation layer is provided. The anode current collector and the cathode current collector are disposed at two opposite sides of the membrane electrode assembly. The hydrophilic and gas-impermeable layer is disposed on the anode current collector. The gas-liquid separation layer is disposed on the hydrophilic and gas-impermeable layer, such that the hydrophilic and gas-impermeable layer is disposed between the gas-liquid separation layer and the anode current collector.

A first transport system moves a web comprising a subgasketed CCM layer and an application system applies a crosslinkable resin to at least a subgasketed portion of the subgasketed CCM layer. The crosslinkable resin preferably comprises a photocurable cationic crosslinkable resin. A first curing apparatus subjects an exposed surface of the crosslinkable resin to a photo curing process to initiate curing of the crosslinkable resin. A second transport system moves a GDL into adhering contact with a partially cured exposed surface of the crosslinkable resin of the CCM layer so as to form an MEA layer. A second curing apparatus subjects the GDL, partially cured crosslinkable resin, and CCM layer structure to a thermal curing process to substantially complete curing of the crosslinkable resin. A converting system is configured to receive the MEA layer and produce a plurality of discrete MEAs from the MEA layer.

A casing of a fuel cell stack has stack deformation prevention structure for limiting the change of an interval between end plates on the lower side in a direction of gravity, due to swelling of the lower side of the stack body in the direction of gravity. The stack deformation prevention structure is configured such that elastic modulus of a side plate provided on a lower side of the stack body in the direction of gravity is higher than elastic modulus of a side plate provided on an upper side of the stack body in the direction of gravity.

A gas diffusion layer for fuel cell of the present invention is structured with a porous member mainly comprised of conductive particles such as acetylene black, graphite and a polymer resin such as PTFE. This makes it possible to achieve both an improvement in power generation performance of the fuel cell and a reduction in costs.
摘要:
A polymer electrolyte fuel cell of the present invention includes a membrane-electrode assembly (5) and separators (6A and 6B). Each of the electrodes (4A and 4B) includes a catalyst layer (2A, 2B) and a gas diffusion layer (3A, 3B). One main surface of the catalyst layer contacts the polymer electrolyte membrane (1). The separator (6A) includes a peripheral portion (16A) and a portion (26A) other than the peripheral portion. The peripheral portion (16A) of the separator (6A) is formed in an annular shape when viewed from a thickness direction of the separator (6A) and is a region including a portion located on an inner side of the outer periphery of the separator (6A). The separator (6A) is configured such that a porosity of the peripheral portion (16A) is higher than that of the portion (26A) other than the peripheral portion.
