摘要: A fuel cell stack includes stacked cells. Each of the cells includes a plastic support frame that supports a membrane electrode assembly at a central portion of the support frame, and includes two separators that sandwich the support frame. The support frame and the two separators each have a through-hole that defines a passage through which fluid flows. An outer surface of each of the two separators in the stacking direction includes a rib. The rib protrudes from an outer edge of the separator and from a peripheral edge of the through-hole of the separator. A shape of the rib on one of the two separators is different from a shape of the rib on the other one of the two separators.

摘要: Fuel cell and power train (FCPT) systems are provided and adapted to being operatively mounted at a tail section of an aircraft fuselage. The FCPT systems will include port and starboard subsystems each being comprised of a nacelle adapted to being laterally attached to a respective side of the tail section of the fuselage, an electric motor contained in the nacelle, a propeller assembly mounted to the nacelle and operatively connected to and adapted to be driven by the electric motor contained therein, and at least one fuel cell positioned in the tail section of the fuselage to supply electrical power to the electric motor contained in the nacelle. One or more hydrogen fuel tanks may be mounted within the tail section of the fuselage to provide a source of hydrogen gas (H2) as fuel to the fuel cells.

摘要: A fuel cell module includes a container and a plurality of cell members radially arranged inside the container. Inside the container, a first fluid flow path through which a first fluid that exchanges heat with an inner portion of the plurality of cell members flows is formed, and a second fluid flow path through which a second fluid that exchanges heat with an outer portion of the plurality of cell members flows is formed. A first heat exchange portion that forms the first fluid flow path and exchanges heat with the cell member has a smaller heat transfer area with the cell member than a second heat exchange portion that forms the second fluid flow path and exchanges heat with the cell member. The first fluid having a larger temperature difference with the cell member than the second fluid flows in the first fluid flow path.
