Abstract
"DISPOSITIVO DE MANUTENçãO DE CéLULA COMBUSTìVEL, APARELHO E MéTODO PARA MANTER TRANSPARENTEMENTE AS CéLULAS DE UM EMPILHAMENTO DE CéLULAS COMBUSTìVEIS". Método e aparelho para manter as células de um empilhamento de células combustíveis são revelados. O aparelho inclui um dispositivo de manutenção de células combustiveis incluindo meio para impor uma baixa impedância através de pelo menos uma célula de um empilhamento de células combustíveis, por exemplo, um comutador, e um gerador de pulso. O gerador de pulso é capaz de pulsar um catodo da pelo menos uma célula através de meios de imposição de baixa impedância, por exemplo, quando o comutador é fechado. O método transparentemente mantém as células de um empilhamento de células combustíveis, e inclui pulsar seqüencialmente os catodos de uma pluralidade de células em um empilhamento de células combustíveis, e manter um número consistente das células provendo energia a uma cara do empilhamento de células combustíveis enquanto seqüencialmente pulsando os catodos da célula.
