A power distribution unit for a vehicle includes a fuel cell stack, a bracket connected to the fuel cell stack and including at least one mount adapted to be connected directly to a vehicle to directly interconnect the fuel cell stack to the vehicle, a connection feature, and a traction system communicated with the fuel cell stack and carried by at least one of the fuel cell stack and the bracket with the connection feature disposed between the traction system and said at least one of the fuel cell stack and the bracket so that the traction system is indirectly connected to the vehicle. In one implementation, the connection feature includes an elastomeric pad disposed between a housing of the traction system and a mount or the vehicle frame. The pad provides a so-called 'soft mount' of the traction system to the vehicle.

A drive unit, such as a rear drive unit, for a motor vehicle, such as an all-wheel drive motor vehicle, includes, but is not limited to two drive shafts, of which one drive shaft serves for driving the one wheel and the other drive shaft serves for driving the other wheel of a motor vehicle. Also provided is a transmission operationally connected to the drive shafts, through which a drive torque acting on the input of the transmission can be divided or is divided into at least two output torques and through which the output torque of the transmission acting on the one drive shaft is reversible or is reversed in its operation direction relative to the output torque of the transmission acting on the other drive shaft.

A fuel cell system that employs one or more PTC ceramic heaters that do not need to be self-regulated, and thus will not require various control components, such as temperature sensors. The PTC ceramic heaters include a ceramic material that is designed for a particular temperature depending on the particular application. An electrical current is applied to the ceramic heater that generates heat as long as the temperature of the ceramic heater is below the designed temperature. If the ceramic heater reaches the designed temperature, then the resistance of the ceramic material goes up, and the current through the ceramic material goes down, so that the heater does not provide significant heating. Therefore, it does not need to be regulated.

One embodiment of the invention includes a product including a fuel-cell exhaust diffuser; an air funnel; and at least two exhaust tubes attached to the diffuser.

An anode inlet unit for a split fuel cell stack or two fuel cell stacks having two anode inlets. The anode inlet unit has particular application for a small vehicle that requires less power. In one embodiment, the anode inlet unit only includes three injectors. Two of the injectors provide flow control for the hydrogen gas to the two anode inlets to provide the desired turn-down ratio. For a split stack design, the two injectors may provide flow-shifting where the injection of hydrogen gas into the sub-stacks is alternated. The other injector injects a small amount of hydrogen into the cathode side of the fuel cell stack at system start-up to quickly increase the operating temperature of the system. Additionally, two valves can be provided in the unit that receive a flow of air to purge the anode side of the stack for system shut-down.
