Fuel cell system used in powering vehicle, such as bus, has T connection provided between first branch and second branch and main cycle

摘要

A two-way reversing valve (112) is arranged in a first branch (102) in front of a pump (110). A connection (116) is arranged in the first branch after the pump. Another connection (118) is arranged in a second branch (108) in front of a heat exchanger (106). A T connection (120) is provided between the first branch and the second branch and a main cycle (70). A heat storage unit (100) is arranged in the first branch parallel to the cooler (74) of a coolant cycle (16). The heat exchanger heated by a heating device (104) is arranged in the second branch parallel to the heat storage unit. The pump is arranged in the first branch in front of the heat storage unit. An independent claim is also included for a process for operating fuel cell system.
