Methods for the prevention of carbon monoxide poisoning in solid polymer fuel cells

Methods for the prevention of carbon monoxide poisoning in solid polymer fuel cells

Methanol is an attractive H2 source for solid polymer fuel cells (SPFCs) in transport applications due to its high on-board energy storage density. Although steam reformation of CH3OH can produce high H2 concentrations (>60%) significant concentrations of CO are also produced in the reaction, i.e...
