    • A method and an apparatus for the investigation of a fuel cell system comprising at least one fuel cell having an anode side to which a fuel is supplied in operation and a cathode side which is separated from the anode side by a membrane and to which an oxidizing agent is supplied in operation, in order to carry out at least one of the following tests: a) to test whether the fuel cell system is gas-tight at the anode side and/or at the cathode side, b) to test whether a leakage is present between the anode side and the cathode side of the fuel cell system, c) to test the starting behavior of the fuel cell system, d) to test the operation of the fuel cell system at low current yield. The respective test is carried out with a mixture of at least inert gas with at least one fuel permissible for the operation of the fuel cells, the mixture being supplied to the anode side of the fuel cell system. The mixture is so selected that the proportion of fuel lies below a value at which the mixture is flammable in air.
    • 一种用于研究燃料电池系统的方法和装置,包括至少一个燃料电池,其具有在运行中供应燃料的阳极侧和通过膜与阳极侧分离的阴极侧,并且氧化 为了进行以下试验中的至少一个试验:a)测试燃料电池系统在阳极侧和/或阴极侧是否气密,b)测试是否 在燃料电池系统的阳极侧和阴极侧之间存在泄漏,c)测试燃料电池系统的启动行为,d)以低电流产量测试燃料电池系统的运行。 相应的试验是用至少一种惰性气体与燃料电池的操作允许的至少一种燃料的混合物进行的,混合物被供应到燃料电池系统的阳极侧。 混合物如此选择,使得燃料的比例低于混合物在空气中易燃的值。
