Abstract

Se proporciona una placa bipolar y apilados de celdas de combustible regenerativos que incluyen las placas bipolares y montajes de electrodo de membrana (los MEA) apilados de manera alternada. La placa bipolar comprende un cuerpo principal de placa formado de un material eléctricamente conductor. El cuerpo principal de placa tiene una primera superficie y una segunda superficie opuesta a la primera superficie. Cada superficie tiene canales de flujo de reacción a través de los cuales pasan fluidos. Los canales de flujo de reacción en la primera superficie tienen una pluralidad de nervaduras entre los mismos formando un patrón de campo de flujo interdigitado. Los canales de flujo de reacción en una segunda superficie tienen una pluralidad de nervaduras entre los mismos formando un patrón de campo de flujo interdigitado o un patrón de campo de flujo diferente de un patrón de campo de flujo interdigitado, por ejemplo, un patrón de campo de flujo en serpentín.
