Fuel cell device having a fuel cell stack including an integrated polarity reversal protection 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.
