A fuel cell module includes a case body containing a cell stack body formed by stacking a plurality of power generation cells. The case body includes a plurality of connectors for mounting the fuel cell module into a fuel cell vehicle. The plurality of connectors include a first connector group used for mounting the fuel cell module into a first fuel cell vehicle in a manner that a stacking direction of the fuel cell module is substantially aligned with a first direction, and a second connector group used for mounting the fuel cell module into a second fuel cell vehicle in a manner that the stacking direction of the fuel cell module is substantially aligned with a second direction. Some connectors are common to both the first connector group and the second connector group.

Stacked bodies each formed by alternately stacking power generation cells and separators are fixed to an end plate, the separators each having a flow passage portion, a gas flow-in port, and a gas flow-out port. The end plate includes upper and lower end plates sandwiching the stacked bodies. The stacked bodies are arranged side by side and a first thermal deformation absorbing portion configured to absorb thermal deformation in a direction orthogonal to a stacking direction is formed between the stacked bodies. Fixing means for fixing the stacked bodies to the end plate fix at least outer peripheral portions of the stacked bodies arranged side by side to the end plate.

A fuel cell system, with an air flow system includes a first thermal zone, a second thermal zone, an air blower provided between the first and second thermal zones. The first thermal zone is connected to an inlet port of the fuel cell system. The second thermal zone is connected to an outlet port of the fuel cell system. The air blower is configured to draw in air from the first thermal zone and provide the air to the second thermal zone.

A fuel cell stack includes an insulating collar member provided in an end plate and screwed with a positioning pin, and a rotation restriction mechanism that restricts rotation of the collar member relative to the end plate in a screw tightening direction of the positioning pin. A method of assembling the fuel cell stack includes a screwing step and a stacking step. In the screwing step, rotation of the collar member relative to the end plate in the screw tightening direction of the positioning pin is restricted by the rotation restriction mechanism.

Herein disclosed is a method of making a fuel cell including forming an anode, a cathode, and an electrolyte using an additive manufacturing machine. The electrolyte is between the anode and the cathode. Preferably, electrical current flow is perpendicular to the electrolyte in the lateral direction when the fuel cell is in use. Preferably, the method comprises making an interconnect, a barrier layer, and a catalyst layer using the additive manufacturing machine.

The invention relates to a housing (10) in which at least one fuel-cell stack (20) is accommodated. The fuel-cell stack (20) comprises a number of electrolyte membranes (54) and bipolar plates (34) arranged one above the other. The housing (10) comprises an inner side (12), which is directed towards the at least one fuel-cell stack (20) and on which is formed a ribbing arrangement (14), which increases the surface area of the housing (10), or individual bipolar plates (34) within the at least one fuel-cell stack (20) have a projecting portion (36). The invention also relates to the use of the housing in a fuel cell having at least one fuel-cell stack (20) for driving an electric vehicle.
