Abstract: A fuel-cell unit cell comprises an MEGA plate with a resin frame, and two separators. There is formed a gas manifold hole in an outer edge portion of the resin frame. There is provided a gas-flow-path forming portion with a recessed-and-protruded shape on the first surface of the resin frame for forming gas flow paths between the gas manifold hole and the first surface of the MEGA. There is also formed a fusion-bonding portion for surrounding a periphery of the gas manifold hole to cut off gas circulation between the gas manifold hole and the second surface of the MEGA and for bonding the resin frame and the second separator with each other, on the second surface of the resin frame so as to pass across a backside of the gas-flow-path forming portion. The fusion-bonding portion is formed from a first resin, and the gas-flow-path forming portion is formed from a second resin higher in melting point than the first resin.

Abstract: A battery includes a battery module provided by covering a group of batteries including arranged cells with an insulating external material, the battery module folded at an area where a conductive member connecting adjacent ones of the cells is located, a case having a hermetically sealing structure to house the battery module, and a coolant passage in which a coolant is passed along a face of the case closest to the conductive member, wherein the case has an internal pressure higher than an external pressure.

Abstract: An electricity storage device includes: a plurality of cells that are aligned in a predetermined direction; a pair of end plates that sandwich the plurality of cells in the predetermined direction; and a restraining member that extends in the predetermined direction, is fixed to the pair of end plates, and exerts a restraining force on the plurality of cells in the predetermined direction via the end plates. Each of the end plates includes a first plate and a second plate. The first plate has a plurality of ribs on a surface that faces the adjacent cell and is formed of insulating material. The second plate is fixed to the first plate on a side opposite to the surface that faces the adjacent cell and is formed of material stronger than the insulating material for the first plate.

Abstract: An electric storage apparatus has a plurality of electric storage stacks placed in line in a second direction (Y direction). Each of the electric storage stacks has a plurality of electric storage elements placed in line in a first direction (X direction) and partition plates each placed between two of the electric storage elements adjacent to each other in the first direction. The electric storage stack is restrained by a restraint unit in the first direction. In adjacent two of the electric storage stacks, two of the partition plates adjacent to each other in the second direction have coupling portions fixed to each other in a plane orthogonal to the first direction and capable of relative movement in the first direction.
