Abstract: For renewable energy technology to become ubiquitous, it is imperative to develop efficient oxygen evolution reaction (OER) electrocatalysts, which is challenging due to the kinetically and thermodynamically unfavorable OER mechanism. In accordance with the purpose(s) of the present disclosure, described herein are iron/nickel carbide compounds that possess unique electrochemical properties. The electrochemical performance of carbides can fine-tuned via Fe incorporation and with control, or suppression, of the growth of the oxide phase on the carbide catalytic surface.

Abstract: An electrode structure includes an electrolyte membrane, a plurality of anode catalyst particles located on an anode side of the electrolyte membrane, a plurality of cathode catalyst particles located on a cathode side of the electrolyte membrane, and a recombination layer located between the electrolyte membrane and the anode catalyst particles. The anode catalyst particles are used for electrolyzing water into a hydrogen ion, oxygen, and an electron. The cathode catalyst particles are used for combining the hydrogen ion and the electron with each other to produce hydrogen. If hydrogen generated on the cathode side of the electrolyte membrane permeates into the anode side across the electrolyte membrane, the hydrogen having permeated is combined with oxygen to turn into water again in the recombination layer. This makes it possible to suppress mixture of hydrogen into oxygen to be output from the anode side.
