Abstract
Improvements to non acid methanol fuel cells include new formulations for materials. The backing material for the fuel cell electrode is specially treated to improve its characteristics. A special sputtered electrode is formed which is extremely porous. Methanol is delivered to the fuel cell through a filter comprising molecular sieves.
