Assemblies and methods for monitoring the voltage condition of a fuel cell device. The monitoring may be provided without direct electrically conductive or mechanical contact with the fuel cell device. This may be provided by a detector coupled to a pair of electrical contacts on a fuel cell device that is adapted to produce electromagnetic energy, or radiation, indicative of the voltage between the pair of electrical contacts. Accordingly, a monitor that is spaced from the detector may be used to detect the produced electromagnetic energy and produce an output signal representative of the voltage difference. In some examples, a plurality of fuel cell devices or overlapping sets of fuel cell devices may be monitored. A digital signal may be generated, providing a simplified indication of the operating condition of one or a plurality of fuel cell devices. Multiple digital signals may be used to provide additional information.
