Methods for the prevention of carbon monoxide poisoning in solid polymer fuel cells
thesis
posted on 2018-01-10, 11:10 authored by Christopher D. DudfieldMethanol 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. up to 2%. CO
preferentially adsorbs on the fuel cell Pt electrocatalyst at typical cell operating
temperatures of 80°C and at such reformer CO output concentrations poisoning of the
electrocatalyst will occur resulting in a dramatic and rapid decrease in fuel cell
performance. Research has therefore been conducted into methods of reducing
electrocatalyst CO poisoning, i.e. chemical CO oxidation prior to the fuel cell and
controlled electrochemical CO oxidation within the fuel cell. [Continues.]
