Predictive control arrangement for load-following fuel cell-powered applications

摘要: A method and system are provided for controlling a fuel cell power plant (10) in predictive manner providing rapid response of the stack assembly (CSA)(12) without creating an unacceptable condition reactant/coolant starvation CSA caused by instantaneous electrical load transients load(s) (20) controllably connected to CSA. demand signal (Mld) representing anticipated current/power required is provided. current (Iap) representative actual drawn The greater selected (46) utilized provide control (Mx, Mx′, Mx′′) regulating one or more reactants coolant (24) effect operating process One status signals (Xp, Xp′, Xp′′, Vap) indicative regulated reactants/coolant and/or respective effected, Each transformed capability (61, 61′, 61′′) which used regulate based on reactant predicted performance during transients. lesser each (62) output (Mi) commensurately (20, 32).
