Porous Electrodes

Simultaneous measurement of the effective ionic conductivity and effective electronic conductivity in a porous electrode film impregnated with electrolyte

“…Ionic and electronic conduction inside such an electrode should be affected by microscopic characteristics, i.e., inherent conductivity of the ionic-and electronic conducting material, volume ratio of each material, shape of the conduction path (tortuosity), etc. [1]. In addition to a consideration of the microstructure, the effective ionic or electronic conductivity can also be defined in terms of macroscopic values, i.e., electric field and apparent ionic and electronic current density.…”

A solid polymer electrolyte-based oxygen sensor for portable oxygen meters

“…With increasing oxygen concentration the influence of convection becomes increasingly important, causing positive deviations from linearity. 5 Also, because of the mass transport mode, the sensor output is directly proportional to the oxygen percentage, instead of the oxygen partial pressure, as in the case of Clark sensors. Besides, within the range Ϯ 30 kPa around the normal atmosphere the output is little influenced by the total pressure.…”

Emergent electrochemical functions and future opportunities of hierarchically constructed metal–organic frameworks and covalent organic frameworks

“…From the viewpoint of electrochemistry history, a porous electrode is a key topic because this system shows largely different properties compared to flat electrodes. 134 As is well known, porous structures exponentially increase the complexity of electrode processes, which is already highly complicated even in flat model surfaces; [135][136][137][138][139][140][141][142] therefore fundamental understanding on the systems, even on well-defined model systems, is not enough so far. 143 However recent rigorous works using a variety of meso-/macroporous metallic electrodes have shown that meso-/macoroporosity can control the electrode process.…”
