This work will provide details on some of the high temperature polymer electrolyte membrane (HTPEM) membrane-electrode-assembly (MEA) performance targets most recently achieved by Danish Power Systems. These include (i) MEA performances of >0.67 V at 0.2 A cm(-2) using dry H-2/Air, (ii) MEA lifetime of 17.000 h at 0.24 A cm(-2) using dry H-2/Air with an average degradation rate of 9 mu V h(-1), and (iii) an integrated 5 kW stack/reformer system using methanol reformate as fuel. Post mortem SEM, TEM, micro-tomography and XRD showed membrane thinning and catalyst particle growth that is typical for PEM fuel cells. Platinum particles grew from an initial 2-3 rim to 6-8 nm at the cathode and 4-5 nm at the anode, while the membrane showed thinning from an undoped 40 mu m-18 gm in some areas after testing. Studies using reformate have also led to promising initial results, while the rate of degradation for an MEA supplied with wet H-2 (30 mol%)/Air for 2000 h was found to be very similar to the rate when supplied with dry H-2. In addition to reaching these performance benchmarks, a reduction in the standard deviation for MEA cell voltage at 0.2 A cm(-2) to <1% has been achieved through efforts aimed at improving the uniformity of the membrane and catalyst layer thicknesses.
