SYSTEMS AND METHODS FOR PROTECTING A FUEL CELL

摘要

The invention relates to hybrid fuel cell systems (100) that protect a fuel cell (10) with a second electrical energy source (106). The second electrical energy source (106) powers a load (108) to prevent the fuel cell (10) from witnessing stoichiometric levels that may lead to reductions in fuel cell performance or health. The hybrid fuel cell system (100) includes an electrical circuit (104) that electrically initiates the electrical energy source to provide power to the load in response to detecting a potential stoichiometric disturbance for the fuel cell (10).
