摘要： The present invention relates to an electrochemical catalyst with a Schottky junction that can be used for selective redox reactions, more specifically, it is configured to forming a Schottky contact on the interface between metals, and metal oxides operating as a semiconductor material to selectively occur oxidation or reduction reactions through Schottky barrier control. Accordingly, the present invention ensures that substantially only oxidation reactions occur in the anode of a fuel cell or a water electrolyzer, while substantially only reduction reactions occur in the cathode and, thereby, has the effects of preventing catalyst degradation and increasing durability.

摘要： 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.

摘要： An electrode structure includes an electrolyte membrane, a catalyst layer, a porous layer, and an ionomer layer. The catalyst layer is formed on a surface of the electrolyte membrane. The porous layer is stacked on an external side of the catalyst layer. The ionomer layer is interposed between the catalyst layer and the porous layer. Thus, it is possible to reduce electrical contact resistance between the catalyst layer and the porous layer.
