T R Bock Dissertation Proton Exchange - professional.
A mathematical model of a proton exchange membrane fuel cell (PEMFC) was developed to investigate the effects of operating parameters such as temperature, anode and cathode pressures, reactants flow rates, membrane thickness, and humidity on the performance of the modelled fuel cell. The developed model consisted of electrochemical, heat energy and exergy components which were later simulated.

Microbial fuel cells (MFCs) use proton exchange membranes (PEMs) to deliver protons to the cathode for electricity production. MFCs have been limited to low power generation because of complex ionic media characteristic of MFCs using the conventional Nafion-based PEM with high attraction for the competing ions. Benthic microbial fuel cells (BMFCs) use the marine sediment between the anode.
To reach this aim, experimentally validated models of a low-power 5-kW proton-exchange-membrane fuel cell and its most power-hungry ancillary (the fuel-cell air-supply system) are described.
