Electrocatalytic H 2 Oxidation Reaction

摘要: Hydrogen (H2), an important material and product in chemical industries, has been investigated as a new clean energy source for many decades [1–3]. With the rapid development of proton exchange membrane (PEM) fuel cell technology, which H2 is used fuel, stored this can be electrochemically converted to electric with zero emissions high efficiency. The dream hydrogen economy era therefore seems closer reality. Beginning 1990s, advantages PEM cells, including zero/low emissions, efficiency, power density, have attracted world-wide research several application areas, automotive engines, stationary generation stations, portable devices [4]. successful demonstrations particular applications, commercialization technology become strong driving force further critical areas cost reduction durability. major platinum (Pt)-based catalysts. At our current technological stage, these Pt-based catalysts both cathodic O2 reaction (ORR) anodic oxidation (HOR) are most practical terms catalytic activity lifetime stability. Therefore, improve stability shot fore recent years. Although theoretical experimental approaches resulted great progress catalysis [2, 3, 5, 6], continuous effort necessary develop breakthrough that cost-effective highly durable commercial use.
