更多例句： 上一页 - Oxygen diffusion transport and electrochemical reaction in the oxygen cathode of direct methanol fuel cell ( dmfc ) have been expressed with the tffa model . model calculation has been carried out to investigate the effects of structural parameters of the dmfc cathode on the electrode performance , which is respectively represented by the curve of cathode overpotential versus current density . much attention has been paid to parameters including the porosity of the reaction layer , the thickness of the thin - film on the flooded - agglomerate , the radius of the flooded - agglomerate , the volume fraction of the flooded - agglomerates in the reaction layer
本文首先运用tffa模型描述直接甲醇燃料电池（ dmfc ）阴极氧气的传递和电化学反应过程，研究了过电位-电流密度曲线受阴极结构参数变化的影响程度，其中着重考虑了以下几个参数：催化层的孔隙率，浸渍聚集体薄膜的厚度，浸渍聚集体的半径，浸渍聚集体在催化层中的体积分数。 - Re also enhanced the deposition potential , polarizability and cathode overpotential of the baths , changed the result of chemical deposition reactions and actuate the deposit of cobalt alloy . and the chemical deposit co - b - re , co - ni - p - re alloy include re which electrode potential is much more negative was obtained . the structure of co - b - re was composed of microcrystal
Re还提高了镀液的静止析出电位、极化度和阴极过电位，改变了化学沉积反应的强弱次序，加强了钴基合金的析出反应，成功地获得了含电极电位较负的re ( la , ce , y )的化学沉积co - b 、 co - ni - p薄膜。
百科释义
Overpotential is an electrochemical term which refers to the potential difference (voltage) between a half-reaction's thermodynamically determined reduction potential and the potential at which the redox event is experimentally observed.Bard, A.
