Kevin Michael Colbow, Marian van der Geest, Cindy J Longley, Jens Müller, Joy Roberts, Jean St Pierre, Peter Urban, Regina Wezel, David P Wilkinson, Jiujun Zhang: Method and apparatus for operating an electrochemical fuel cell with periodic reactant starvation. Ballard Power Systems, McAndrews Held & Malloy, October 29, 2002: US06472090 (28 worldwide citation)

An electrochemical fuel cell is operated with periodic reactant starvation at either or both electrodes. Periodic reactant starvation conditions cause a change in the potential of the starved electrode and may result in the removal of electrocatalyst poisons and in improved fuel cell performance. Th ...
