摘要： A bipolar secondary battery is provided with an electric power generating unit, a pair of terminal plates. The electric power generating unit includes a plurality of bipolar electrodes stacked on one another with an electrolyte layer disposed between the bipolar electrodes and separating the bipolar electrodes. Each of the bipolar electrodes includes a collector with a positive electrode active material layer formed on a first side surface of the collector, and a negative electrode active material layer formed on a second side surface of the collector. The first terminal plate is connected to a first stacking direction facing end of the electric power generating unit. The second terminal plate is connected to a second stacking direction facing end of the electric power generating unit. At least one of the terminal plates includes an electric current suppressing device that suppresses an electric current occurring when an internal short circuit occurs in the electric power generating unit.

摘要： A fuel cell stack is provided having a plurality of unit cells stacked in a horizontal direction. Each unit cell includes an electrolyte membrane having two surfaces and a peripheral edge, electrodes provided on both surfaces of the electrolyte membrane, frame-shaped members provided on both surfaces of the electrolyte membrane adjacent to the respective electrodes and adjacent the peripheral edge of the electrolyte membrane, separators provided on the electrodes and the frame-shaped members and having a reactant gas passage for supplying a reactant gas to each of the electrodes, and a manifold formed in the stacking direction in fluid communication with the reactant gas passage. The manifold includes a horizontal edge portion in fluid communication with the reactant gas passage.

摘要： First reinforcing members, having a low modulus of elasticity, are disposed between an electrolyte membrane and second reinforcing members having a high modulus of elasticity, so as not to allow the electrolyte membrane to readily rub against the first reinforcing members as the electrolyte membrane expands and shrinks and to ultimately prevent degradation of the electrolyte membrane.
