摘要： 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.

摘要： A fuel cell system having a fuel cell stack in a housing includes a compressor that provides compressed ambient air to the fuel cell stack and a ventilation system coupled to a suction side of the compressor to provide ventilation of the housing and cool an associated voltage monitoring unit that may be located within the housing or upstream of the housing. The ventilation system may control a valve to supply air from the compressor outlet to the housing to warm the housing and stack when either or both have a temperature below an associated threshold. The ventilation system may include a second valve to control exhaust from the housing based on the temperature of the housing or stack. Stack exhaust may drive a turbine coupled to the compressor. A heat exchanger may be positioned to cool compressed air from the compressor before flowing to the stack.

摘要： A tank assembly for a motor vehicle includes an axially extending compressed gas tank having a middle portion and axially terminal end portions, and a tank support configured to fasten the compressed gas tank to a vehicle body. The tank assembly has a guard device that catches the compressed gas tank in the event the tank and/or support become partially or fully detached from the vehicle. A guard support is configured to secure the guard device to the vehicle body. A retaining element forms an axial stop for a first end portion, and at least one pliable tension element, which extends axially and connects the retaining element to the guard support in a tension-transmitting manner.
