Abstract

Mejoras en el uso de metal en catalizadores soportados que contienen metal para celdas de combustible. Por ejemplo, la presente se refiere a métodos para dirigir y/o controlar la deposicion de metal sobre las superficies de sustratos porosos. La presente también se refiere a métodos para preparar catalizadores para celdas de combustible donde se deposita un primer metal sobre un soporte (por ejemplo, un soporte de carbono poroso) para proveer una o más regiones de un primer metal en la superficie del soporte, y se deposita un segundo metal en la superficie de las una o más regiones del primer metal. En general, el carácter electropositivo del primer metal (por ejemplo, cobre o hierro) es mayor que el carácter electropositivo del segundo metal (por ejemplo, un metal noble tal como platino) y el segundo metal se deposita en la superficie de las una o más regiones del primer metal por desplazamiento del primer metal. La presente también se refiere a sustratos tratados, estructuras precursoras del catalizador y catalizadores para celdas de combustible preparados por dichos métodos. La solicitud también se refiere al uso de catalizadores preparados segun se detalla aquí en celdas de combustible.
