Stanford, VW researchers use ALD to build OER electrodes for high-power-density fuel cells
A team from Stanford University and Volkswagen Group Research in Wolfsburg, with colleagues from McMaster University in Canada, the University of Delaware, SINTEF and the Norwegian University of Science and Technology have used an atomic layer deposition-facilitated electrode fabrication technique to build electrodes for the oxygen reduction reaction (ORR) in high-power-density PEM fuel cells.
In a paper published in the journal
Cell Reports Physical Science, the researchers report that the combination of an agglomerated ionomer dispersion and a mesoporous support gives access to a high catalytic activity (mass activity [MA] = 0.31 A/mgPt with pure Pt) that can be maintained at high current densities.
