Porous micro-ring electrode - Preparation and investigation of methanol oxidation

Abstract

We have developed a porous micro-ring electrode, which conventionally represents a part of membrane electrode assembly (MEA) of proton exchange membrane (PEM) fuel cell The porous micro-ring electrode has a PEM/electrocatalyst layered structure at a tip of a glass capillary. This electrode has proven to exhibit electrocatalytic properties. Moreover, the methanol oxidation reaction at the PEM/electrocatalyst could be measured and evaluated.
