A fuel cell containing fuel for an aircraft includes an innermost layer configured to contact the fuel, an outermost layer and a containment gel formed from isocyanate and polyol interposed between the innermost and outermost layers. The containment gel is configured to self-seal a ballistically formed hole therein, thereby reducing leakage of the fuel from the fuel cell.

A vehicle includes at least one fuel cell stack, a water reservoir housed higher than the at least one fuel cell stack, a first water pump, a second water pump and a control module. The at least one fuel cell stack is operable to generate electrical energy and water. The water reservoir is operable to store water. The first water pump is operable to pump water from the at least one fuel cell stack into the water reservoir against gravity. The second water pump is operable to dispense water from the water reservoir under assistance from gravitational potential energy of water in the water reservoir. The control module is configured to operate the second water pump on an on-demand basis, and operate the first water pump on a time-selective basis.

A fuel cell case includes: a casing portion provided with a through hole that communicates between an internal space for accommodating a fuel cell stack and outside of the casing portion; a lid portion attached to an outer surface of the casing portion by a first connection portion so as to close the through hole; and a cover portion arranged on the lid portion and attached to the outer surface of the casing portion. It is configured that at least one of the lid portion and the first connection portion is fractured when an internal pressure of the casing portion is increased to be equal to or higher than a predetermined pressure and that the cover portion remains to be attached to the casing portion even after at least one of the lid portion and the first connection portion is fractured.

In a control device for a power converter converting electric power of a fuel cell stack, the power converter includes first and second reactors, a first switching element connected to the first reactor, and a second switching element connected to the second reactor. The second reactor is located closer to a cooling water discharge manifold than the first reactor. The control device configured to: set first and second duty cycles of the first and second switching element; and execute limit control in which, by controlling the setting of the first and second duty cycles, a second amount of heat generated by the second reactor due to a second current is limited to a value smaller than a first amount of heat generated by the first reactor due to a first current within a period of at least multiple ON-OFF cycles of the first and second switching elements.

A fuel cell vehicle capable of determining, when a fuel cell vehicle collides with a rigid body, whether a stack is damaged by a visual observation at a low cost. A fuel cell vehicle includes: a fragile part configured to be located so as to come into contact with a side surface of the stack frame that is orthogonal to a direction in which cells in the stack are stacked, and be deformed when a preset collision force causing damage to a stack is applied; and a deformation part configured to form a part of the vehicle body, and be deformed and come into contact with the fragile part when a collision force is applied to the vehicle body.
