Abstract:
1. A method for the investigation of a fuel cell system, said fuel cell system having an anode side to which a fuel is supplied in operation and a cathode side to which an oxidizing agent is supplied in operation and comprising at least one fuel cell, each said fuel cell having an anode, a cathode and a membrane separating said cathode from said anode, said method comprising a first test comprising at least one of the following tests: a) to test whether said fuel cell system is gas-tight at said anode side and/or at said cathode side, b) to test whether a leakage is present, between said anode side and said cathode side, c) to test a starting behaviour of said fuel cell system, or d) to test an operation of said fuel cell system at low current yield,
