Abstract
A proton exchange membrane fuel cell includes an anode catalyst layer, a cathode catalyst layer, a proton exchange membrane separating the anode catalyst layer from the cathode catalyst layer, an oxygen inlet configured to supply oxygen to the cathode catalyst layer, and a hydrogen inlet separate from the oxygen inlet and configured to supply hydrogen to the anode catalyst layer. The fuel cell is operable to convert the hydrogen from the hydrogen inlet to hydrogen ions at the anode catalyst layer and to produce an H2O byproduct at the cathode catalyst layer where the oxygen reacts with the hydrogen ions. The fuel cell includes a water outlet for the H2O byproduct that is separate from the oxygen inlet.
