Mathematical modelling of the catalyst layer of a polymer-electrolyte fuel cell
, 2007 In this paper we derive a mathematical model for the cathode catalyst layer of a polymer electrolyte fuel cell. The model explicitly incorporates the restriction placed on oxygen in reaching the reaction sites, capturing the experimentally observed fall ...
