Abstract
A fuel cell () includes a cathode catalyst () for receiving a first reactant and an anode catalyst () for receiving an expected amount of a second reactant. The cathode catalyst () and the anode catalyst () respectively catalyze the first reactant and the second reactant to produce an electrochemical reaction that generates a flow of electrons between the cathode catalyst () and the anode catalyst () The amount of the first reactant consumed in the electrochemical reaction corresponds to a threshold amount of the second reactant needed to generate a forward flow of the electrons from the anode catalyst () to the cathode catalyst (). A portion () of a fuel cell flow field includes a feature (, W, D) that restricts consumption of the first reactant.
