Fuel cell system has fuel cell stack with integrated polarity inversion protection diode on or in end plate with cooling device in end plate near diode and in thermal contact with diode

摘要

The system has a fuel cell stack (2) with a number of fuel cells between two end plates, an electrical load (3) connected to the stack via a load circuit (5) and a diode (6) connected in the load circuit between the stack and load. The diode is arranged on or in an end plate with a cooling device in the end plate near the diode and in thermal contact with the diode.
