Fuel cells PEMFC

This volume assesses the current status of PEMFC fuel cell technology, research and development directions, and the scientific and engineering challenges facing the fuel cell community. It demonstrates how the production of a commercially viable PEMFC requires a compromise of materials with adequate properties, design interaction, and manufacturability.

Figure 3.3.8 Schematic illustration of the origin of activation overpotentials in a hydrogen-oxygen fuel cell. The solid curves represent exponential analytic current densities versus electrode potential of the hydrogen electrode (standard potential 0 V) and the oxygen electrode (standard potential 1.23 V). Relevant for a PEMFC fuel cell are the HOR (anode) and the ORR (cathode) branches. To satisfy a cell current (yceii), the anode potential moves more positive by riact,HOR> while the cathode potential moves more negative by iiact.oRR- As a result of this, the observed cell potential is V, which is smaller than 1.23 V. The shape of the individual characteristics is such that the cathode overpotentials are larger than those at the anode.

Fig. 23. Fuel processor configuration with a low temperature PEMFC fuel cell (courtesy ECN).

Figure 23 gives a simplified configuration of a fuel processor with a PEMFC fuel cell configuration, emphasizing the catalytic reactors that are present. 

For this application, the reaction pressure in the system is usually just above atmospheric, enough to overcome the pressure drop within the system. In this case, the fuel that is used is a diesel fuel that is converted first in the ATR. The resulting syngas is then purified in a number of steps before the reformate is fed to a PEMFC fuel cell. This configuration is envisaged in an APU application on board of cars, boats, or recreational vehicles.
