摘要:
A fuel cell system that includes a fuel cell stack, and energy storage that is coupled to the fuel cell stack, and a switch that is coupled between the energy storage and the fuel cell stack. The fuel cell system also includes a controller to measure at least one current to determine a likelihood of a current flowing from the energy storage to the stack at a later time and based on the determination, operate the switch to prevent the current.
摘要:
A fuel cell system includes a fuel cell stack, energy storage and a control subsystem. The energy storage supplements a power that is provided by the fuel cell stack. The energy storage is coupled to the fuel cell stack and has a voltage. The control system regulates a peak of the voltage based on a temperature of the energy storage.

A fuel cell system includes a fuel cell stack, energy storage and a control subsystem. The energy storage supplements a power that is provided by the fuel cell stack, and the energy storage is coupled to the fuel cell stack and has a voltage. The control subsystem monitors the energy storage for a leakage and takes an action in response to detecting the leakage.
摘要:
A technique includes introducing an electrical perturbation to a fuel cell system during operation of the fuel cell system. This electrical perturbation does not substantially disrupt the operation of the fuel cell system. In response to the perturbation, an electrical parameter of the fuel cell system is measured.
摘要:
A fuel cell system includes a fuel cell stack, a DC-to-DC converter and at least one capacitor. The fuel cell stack provides a stack voltage, and the DC-to-DC converter receives the stack voltage. The capacitor(s) are coupled between the fuel cell stack and the DC-to-DC converter.
