摘要： Provided is a fuel cell capable of maintaining an interface pressure in good condition between a membrane electrode assembly and separators, and preventing an increase in contact resistance. A fuel cell is disclosed including: a membrane electrode assembly provided with a frame at a periphery thereof; two separators holding both the frame and the membrane electrode assembly therebetween; and a gas seal provided between an edge portion of the frame and an edge portion of each separator to have a configuration in which a reactant gas passes through the frame and the membrane electrode assembly and the separators, wherein the frame and the separators are not in contact with and separated from each other in a region between the membrane electrode assembly and the gas seal.

摘要： Provided is a fuel cell including: a membrane electrode assembly (30) formed by joining an anode (32) to one surface of an electrolyte membrane (31) and joining a cathode (33) to another surface of the electrolyte membrane (31); a frame body (20) formed integrally with the membrane electrode assembly (30); and a pair of separators (40, 41) holding the membrane electrode assembly (30) and the frame body (20) therebetween. At least one pair of holding pieces (42, 43) holding the membrane electrode assembly (30) therebetween is formed in the pair of separators (40, 41). Positions of holding end portions (42a, 43a) of the pair of holding pieces (42, 43) are shifted from each other in a stacking direction of the fuel cell.

摘要： A high-pressure gas container (100) includes an inner layer (11) configured such that high-pressure gas is filled inside, a boss part (13-1, 13-2) provided at least at one position of the inner layer and configured to cause the gas to flow in and out, and an outer layer (12) configured to cover an outer periphery of the inner layer to reinforce the inner layer and having a higher gas barrier property than the inner layer. A gas discharge port (15-1, 15-2) is provided between the boss part and the outer layer, and a gas ventilation part (14) is formed between the inner layer and the outer layer such that the gas having permeated through the inner layer is discharged into atmosphere through the gas discharge port.
