Critical Issues

Proton exchange membrane (PEM) fuel cells are among the most promising fuel cell technologies. Recent experimental and numerical investigations [1–3] on PEM fuel cells (PEMFC) identified water management as one of the most critical issues for designing robust, high-performance PEM fuel cells. Proper water management within the cell is therefore essential, as dehydration of the membrane or flooding of the cathode result in increasing resistive losses. Flooding reduction in the fuel cell is commonly done by removing water with excessive reactant (H2 or O2) flow rates and elevated gas pressures. This mixture makes air delivery the largest parasitic load on fuel cells. Typically, this type of air delivery consumes more than 20% of the fuel cell power. As an alternative, we have developed a novel biased AC electroosmtic micropump for PEM fuel cell applications that can be fabricated with micro-electro-mechanical-systems (MEMS) compatible semiconductor micro-fabrication. This research paper will experimentally demonstrate the bi-directional pumping action that can prevent flooding, increase power density, and ensure stable performance of fuel cell by removing water from flooded regions and redistributing it to under-saturated regions.

The fast decay in PEM fuel cells of a highly active, high performance, but unstable Fe/N/C catalyst like our NC_Ar + NH3 follows a chemical, not an electrochemical, demetallation mechanism for its ORR active FeN4 sites in the catalyst micropores.
