Abstract:
1. A fuel cell for generating electrical energy, the fuel cell comprising: an anode having an anode flow field for flowing hydrogen across the anode; an anode catalyst applied to one side of the anode and configured to split the hydrogen into protons and electrons; a cathode having a cathode flow field for flowing oxygen across the cathode; a cathode catalyst configured to split an oxygen molecule into a pair of oxygen atoms and applied to one side of the cathode such that it opposes the anode catalyst, wherein the cathode catalyst is formed of a plurality of nanoparticles, and each nanoparticle has a plurality of terraces formed of platinum surface atoms, and a plurality of edge regions and corner regions formed of atoms of a second metal; and an electrolyte between the anode catalyst and the cathode catalyst, and configured to allow protons from the anode to pass to the cathode and forcing electrons from the anode to travel along an external circuit and produce electrical power, wherein the protons combine with oxygen atoms at the cathode to form water.
