Abstract

"USINA DE ENERGIA A CéLULA DE COMBUSTìVEL". Uma carga auxiliar (148) para uma pilha de célula combustível (102) é alternativamente conectada e desconectada do circuito externo (177,178) da célula de combustível por um comutador (200) em resposta a um controle de comutador (201) repetidamente, durante a partida e da paralisação. O comutador pode ser um transistor bipolar a porta isolada (208) que é ativado e desativado pela oscilação entre uma voltagem limite superior (207) e uma voltagem inferior (208), que pode ser efetuado por circuitos de comparação (205, 206), pelo controlador (202), ou por comutadores de histerese responsivos à voltagem comercialmente disponíveis. Programas de ciclo de serviço em função da voltagem de pilha de célula para partida (212) e paralisação (213) controlam um modulador por impulsos em duração (PWM) (215) que opera o comutador. Controles (229, 231) podem limitar a modulação para que a carga auxiliar não superaqueça, em resposta à temperatura (221) da carga ou de modelo de voltagem/potência (235). A carga auxiliar pode compreender um aquecedor em um acumulador de água (247), uma tomada de ar (257) ou um aparelho de recuperação de entalpia (262).
