Polyaniline-derived Non-Precious Catalyst for the Polymer Electrolyte Fuel Cell Cathode

This paper focuses on a new polyaniline-derived non-precious cathode catalyst with high oxygen-reduction activity, verified in electrochemical and fuel cell testing. The rotating disk (RDE) onset and half-wave potential (E1⁄2) of oxygen reduction were measured at 0.90 V and 0.77 V, respectively. Rotating ring-disk electrode (RRDE) study revealed very good selectivity in the fourelectron reducti...

High‐Performance Direct Methanol Fuel Cells with Precious‐Metal‐Free Cathode

Direct methanol fuel cells (DMFCs) hold great promise for applications ranging from portable power for electronics to transportation. However, apart from the high costs, current Pt-based cathodes in DMFCs suffer significantly from performance loss due to severe methanol crossover from anode to cathode. The migrated methanol in cathodes tends to contaminate Pt active sites through yielding a mix...

Development of a metal oxide cathode catalyst for air- cathode microbial fuel cells

Microbial fuel cell (MFC) converts the organic compounds to electricity. The higher cost of the cathode catalyst for oxygen reduction reaction (ORR) is one of the major limitations in the technology. Therefore, the study endeavored to introduce a novel cathode catalyst i.e. porous Co3O4 flakes for ORR in MFCs. The flakes exhibited the micropore surface area of 1.0372 m2/g. The MFC with cobalt o...

High catalytic activity and pollutants resistivity using Fe-AAPyr cathode catalyst for microbial fuel cell application

For the first time, a new generation of innovative non-platinum group metal catalysts based on iron and aminoantipyrine as precursor (Fe-AAPyr) has been utilized in a membraneless single-chamber microbial fuel cell (SCMFC) running on wastewater. Fe-AAPyr was used as an oxygen reduction catalyst in a passive gas-diffusion cathode and implemented in SCMFC design. This catalyst demonstrated better...

Neutral hydrophilic cathode catalyst binders for microbial fuel cells†

Improving oxygen reduction in microbial fuel cell (MFC) cathodes requires a better understanding of the effects of the catalyst binder chemistry and properties on performance. A series of polystyrene-bpoly(ethylene oxide) (PS-b-PEO) polymers with systematically varying hydrophilicity were designed to determine the effect of the hydrophilic character of the binder on cathode performance. Increas...
