Abstract
Electrocatalysts for the anode electro-oxidation of formic acid in direct formic acid fuel cells (DFAFCs). The Pd-, Pt- or PdPt-based electrocatalysts contain WO3-modified ordered mesoporous carbon (OMC) as support material. Compositions and ratios of Pd:Pt in the electrocatalysts as well as methods of preparing and characterizing the catalysts and the WO3-OMC support material.
Claims20
An electrocatalyst for a fuel cell electrode comprising:
- nanoparticles of Pd as a first catalytic metal;
- nanoparticles of Pt as a second catalytic metal;
- and
- a catalyst support material comprising nanoparticles of an ordered mesoporous carbon and nanoparticles of WO3;
- wherein the Pd and Pt nanoparticles are present in a ratio of x:y and x>y.
