Title
(PT) SISTEMA DE CÉLULA DE COMBUSTÍVEL
Abstract
(PT) SISTEMA DE CÉLULA DE COMBUSTÍVEL. A presente invenção compreende uma pluralidade de células de combustível conectadas entre si em série, e um reformador configurado para reformar combustível bruto, em que o combustível reformado pelo reformador é suprido para um primeiro estágio da pluralidade de células de combustível, e a célula de combustível no primeiro estágio é dotada de uma função de supressão de reação de metano que suprime a reação de metano incluído no combustível reformado em uma proporção maior do que pelo menos uma célula de combustível em um segundo estágio e em estágios posteriores. A supressão da queda de temperatura devido à reação endotérmica na célula de combustível no primeiro estágio pode aprimorar a eficiência de geração de energia elétrica do sistema de célula de combustível que tem a pluralidade de células de combustível disposta em série.
