Abstract
A fuel cell system includes a fuel cell stack, a housing, a first coolant port, a second coolant port, and a cooling device having a coolant pump and a heat exchanger in fluid communication with the coolant pump. The housing includes an upper side and a bottom side. The fuel cell stack is arranged inside the housing. The first coolant port and the second coolant port each comprise a coolant tube having an inner tube, an outer tube and a gap therebetween. Each of the first coolant port and the second coolant port reach through the housing in a way that an inner end is further to the upper side than an outer end. The first coolant port and the second coolant port are coupled to the cooling device and a first coolant path of the fuel cell stack to form a coolant loop.
