Fuel cell stabilisation system and method

A fuel cell stabilization system for stabilizing the supply of electrical power from a fuel cell stack to a DC bus within a selected operating range, comprising a control configured to limit electrical power drawn from the DC bus by a housekeeping supply, which is configured to power one or more housekeeping elements, based on a stabilization signal representing the supply of electrical power being outside the selected operating range.

A fuel cell stabilization system for stabilizing the supply of electrical power from a fuel cell stack to a DC bus, comprising a control configured to enable a loadbank to draw electrical power from the DC bus.

A method for stabilizing the supply of electrical power from a fuel cell stack to a DC bus within a selected operating range, which method comprises:

• detecting a DC bus voltage on the DC bus;
• and
• increasing an electrical power flow to the DC bus from a DC power supply as required, based on a stabilization signal representing the supply of electrical power being outside the selected operating range.
