Abstract:
A measuring routine for monitoring the operating state of a fuel cell arrangement consisting of at least one fuel cell, in which the fuel cell arrangement has an operating load connected to it, at least one power amplifier for supplying at least one low-frequency signal (s e1 (t), s e2 (t)) is further provided, the output of which is coupled to the fuel cell arrangement, and having an evaluation device, likewise coupled to the fuel cell arrangement, for capturing a signal response s ai (t) to the at least one supplied signal s ei (t), wherein the fuel cell arrangement ( 1 ) has two or more individual signals (s e1 (t), s e2 (t)) at different frequencies (f e1 , f e2 ) supplied to it and the evaluation device is set up to capture the signal response s ai (t) for selected frequencies (fa 3 , fa 4 ) of the intermodulation products (mfe 1 +/−nfe 2 ) of the supplied individual signals (s e1 (t), s e2 (t)) and to measure at least the amplitude of said signal response in order to obtain at least one output signal (S AZ , S′ AZ , S″ AZ ).

Claim (Index 1):
A method for monitoring the operating state of fuel cells, in which a fuel cell arrangement comprising:\n at least one fuel cell is provided with a signal (s 1 (t), s 2 (t)) in the low-frequency range and the occurring signal response s ai (t) is measured and evaluated, wherein the provided signal comprises two or more individual signals (s 1 (t), s 2 (t)) of different frequencies (f 1 , f 2 ), the signal response s ai (t) is measured at selected frequencies (f 3 , f 4 ) of the intermodulation products (mf 1 +/\u2212nf 2 ) of the provided individual signals and the measured intermodulation signals (si 1 , si 2 ) are used to assess the operating state.
