Research of degradation mechanism of the membrane-electrode assemlies of solid polymer water electrolyzer

Concerning performance, safety, reliability and durability issues, the membrane-electrode assembly (MEA) is probably the weakest cell component. Most performance losses and most accidents occurring during PEM water electrolysis are usually due to the MEA. The purpose of this article is to report on specific degradation mechanisms of the MEA and electrolyser in whole.

Influence of additive in electrolytic production of zinc electrode on its electrical characteristics

We have studied the influence of brighteners used in zinc electroplating on the characteristics of zinc powder, which produced in the manufacture of electrolytic zinc electrode. Their effect was determine on the cathodic process, the nature of spongy zinc deposits, corrosion of the zinc electrode and capacity characteristics with intense discharge in a nickel-zinc accumulator.
