Polarization measurement is one of the major electrochemical methods used by electrochemists. The changes in current/potential with time at constant potential/current are investigated. The outcomes of these observations can be used to plot a current

A new easy-to-use process for obtaining fine powders of lanthanum-based perovskite-type oxides (La1−xAexMO3: Ae = Ca, Sr, M = Mn, Co, Fe) with a high specific surface area was successfully developed by the use of polyvinyl pyrrolidone (PVP) as a di

An indirect fuel cell system is constructed. The system is composed of a redox flow battery (RFB) to extract electrical energy and two chemical reactors (anolyte and catholyte regenerators). A quinone as a redox mediator is reduced by a mixture of hy

The adsorption of a porphyrazine (a tetraazaporphyrin) on the surfaces of Pt nanoparticles enhanced the activity of the oxygen reduction reaction (ORR) of the Pt catalysts for use in a polymer electrolyte fuel cell (PEFC). The apparent electrochemica
