Abstract
The performance of a fuel cell power plant that decays, in an electric vehicle which makes frequent starts, is recovered by partially shutting down the power plant. Recovery is enabled by a recovery enable flag upon conditions such as vehicle using low or no power, vehicle speed at or near zero, electric storage SOC above a threshold, and no recovery during the last half-hour (or other duration). The recovery restart resets a timer to ensure that recovery is not attempted too often. The power plant then remains in a recovery stand-by mode until a recovery restart flag is set to 1. The restart causes start-up of the fuel cell power plant, reaching an operational mode.
