nanoporous silicon, fuel cell, formic acid
In this paper the formation of nanoporous silicon membranes and evaluation of their usage for the solid electrolyte in miniature direct formic acid fuel cells compatible with silicon micro-fabrication technology is reported. Nanoporous silicon membranes with different thickness and different pore sizes were fabricated, and micro fuel cells with these membranes were fabricated and tested for their performances.
