A fuel cell system including an anode, a cathode, a first passage, and a second passage, wherein the anode is disposed in the first passage and the cathode is disposed in the second passage, an evaporator, fluidly communicating with the first passage, for evaporating an aqueous mixture including at least one oxidizable component to form a gaseous feed, and a controller, communicating with the fuel cell for receiving an anode corrosion indication, and configured to effect deliver the gaseous feed to the first passage to form a first gaseous stream flowing through the first passage in response to the anode corrosion indication within the fuel cell.
