Abstract: A fuel cell vehicle includes a fuel cell assembly with at least a first fuel cell stack and a second fuel cell stack. Waste gas extracted from the first fuel cell stack is routed to an input of the second fuel cell stack. The first and second fuel cell stacks may be of the same size or the second fuel cell stack may be sized smaller than the first fuel cell stack.

Abstract: A fuel cell system includes a fuel cell, a cooling system fluidly coupled to the fuel cell and having a heat exchanger, a coolant pump, and a coolant reservoir fluidly coupled to the heat exchanger and the coolant pump, a supply system configured to supply a gas containing oxygen to the fuel cell, and a valve positioned in a connecting line between the cooling system and the supply system, the valve operable to limit a pressure difference between pressure of the gas supplied to the fuel cell and pressure within the cooling system.

Abstract: A method for producing a compressed gas tank for a motor vehicle includes inserting a bundle of heat-conducting elements through an opening in a housing of the compressed gas tank and exerting a force on the bundle that radially expands the bundle within the housing beyond the size of the opening. The heat-conducting elements may be helically wound about a central axis when inserted through the opening with a torsional force applied to unwind the elements while radially expanding and reducing axial length of the bundle. A compressed gas tank for a motor vehicle includes a plurality of heat-conducting elements including at least one tube within a tank housing that extend axially along the tank and radially within the housing to a size exceeding an opening of the housing. The tube is configured to circulate coolant to cool compressed gas within the tank.

Abstract: A pressurized gas tank for a motor vehicle includes a cylindrical axially extending housing with two end pieces axially connected thereto connected together by one or more tie rods configured for axial transmission of tensile force. The tie rods include an axially continuous through-channel configured to be connected to a vehicle cooling system including a circulating liquid coolant to cool the pressurized gas at least during refueling of the pressurized gas tank.
