1. A fuel cell system, comprising:

  • a fuel cell stack;

    at least one sensor proximate the fuel cell stack to detect an operating parameter of the fuel cell stack;

    at least one actuator; and

    a microcontroller coupled to receive signals from the sensor and to provide signals to the actuator and configured to perform a self test by;

    setting a set of bits in a number of general registers of the microcontroller to a predefined pattern;

    complementing the set of bits of one of the general registers;

    copying the set of bits from the one of the general registers to a special register of the microcontroller;

    determining if each bit in the set of bits copied to the special register was complemented; and

    producing a notification signal based on the determination.
