Development and Characterization of Direct Formic Acid Fuel Cell for Potable Power Applications
… determine the spatial distributions of water and fuel in the membrane and GDL's of operating DFAFC. MRI images taken with a 14.7 T imaging system, show that the fuel distribution with the operating fuel cell is non-uniform. Generally, there is more fuel in the bottom of the cell, while the upper …

Synthesis and Characterization of Platinum-Based Fuel Cell Catalysts
Highly active Pt-based nanoparticle fuel cell catalysts were synthesized and explored by electrochemical NMR (EC-NMR). Pt/Ru catalysts were obtained by spontaneous deposition of Ru onto platinum nanoparticles. Their reactivity toward methanol oxidation maximized at ruthenium packing density …
