摘要: A fuel cell stack includes a stacked body including a plurality of power generation cells stacked in a stacking direction. Insulation members and end plates are provided to sandwich the stacked body therebetween in the stacking direction. A coolant passage is provided between each of the insulation members and each of the end plates. The coolant passage includes a first coolant passage and a second coolant passage. A surface area of a region in which the first coolant passage is provided is larger than a surface area of a region in which the second coolant passage is provided. A flow rate of the coolant flowing through the first coolant passage is larger than a flow rate of the coolant flowing through the second coolant passage.

摘要: A fuel cell stack includes a stacked body, a first insulator and a second insulator. The stacked body includes power generation cells. The power generation cells are stacked in a stacking direction. The power generation cells include a first end power generation cell a second end power generation cell. Each of the power generation cells includes a membrane electrode assembly, a cathode separator and an anode separator. The first end power generation cell has an outermost cathode separator. The second end power generation cell has an outermost anode separator. The first insulator has a first recess in which a first heat-insulating body and a first terminal plate are accommodated. The second insulator has a second recess in which a second heat-insulating body and a second terminal plate are accommodated. A first number of first stacked heat-insulating layers is larger than a second number of second stacked heat-insulating layers.

摘要: A fuel cell stack includes a terminal plate, an insulating member, and an end plate at one end of a stack body formed by stacking a plurality of power generation cells. A heat insulating member and the terminal plate are placed in a recess of the insulating member. The heat insulating member is formed by stacking metal plates and metal plates together alternately. The metal plate is formed by cutting the outer end of a first metal separator of the power generation cell into a frame shape and the metal plate is formed by cutting the outer end of a second metal separator of the power generation cell into a frame shape.

摘要: A fuel cell stack includes a stack body formed by stacking a plurality of fuel cells together in a stacking direction. A second end plate is provided at one end of the stack body in the stacking direction. A pair of coolant supply passages are provided at upper and lower positions of the second end plate for allowing a coolant to flow into the fuel cells. A coolant supply manifold member is attached to the second end plate, and an insulating plate is provided between the second end plate and the coolant supply manifold member.

摘要: A fuel cell stack includes unit cells, a resin load receiver, and a connecting member. The resin load receiver is provided in each of a first and second separators. The resin load receiver has a projecting portion that projects outwardly from an outer peripheral edge of each of the first and second separators and that has a projecting portion lateral face. The connecting member includes an engagement portion engaged with the resin load receiver and having a depressed portion into which the projecting portion is inserted and which has a depressed portion lateral face facing the projecting portion lateral face. A distance between the projecting portion lateral face and the depressed portion lateral face at a root portion of the projecting portion is smaller than a distance between the projecting portion lateral face and the depressed portion lateral face at an end of the projecting portion.
