Erosion behavior of nickel diffusion membranes in conditions of water electrolysis
Preliminary studies of the erosion resistance of Ni diffusion membranes under the conditions of water electrolysis in various modes were carried out. Particular attention was paid to the time dependencies of the current, voltage and the electrolyte temperature during the process. Both electrodes, an...

Low temperature plasma and plasma technologies Preliminary studies of the erosion resistance of Ni diffusion membranes under the conditions of water electrolysis in various modes were carried out.

Проведено попередні дослідження ерозійної стійкості дифузійних мембран з Ni в умовах електролізу води в різних режимах. Особливу увагу було приділено вимірюванню залежності струму та напруги на електродах, температури електроліту від часу процесу. Обидва електроди, анод та катод, були виконані у вигляді трубок з Ni-99,5 ваг.%. Як електроліт використовували чисту воду після фільтра з мінералізацією 14 проміле, а також воду з додаванням соди (мінералізація 140...160 проміле). Показано, що катоди після декількох годин роботи не виявили жодних ознак ерозії чи інших ушкоджень. Ступінь ерозії оцінювали шляхом зважування, а стан (морфологію) поверхні візуально за допомогою оптичного мікроскопа. Що стосується анода, навіть при електролізі достатньо чистої води (14 проміле), спостерігається суттєва ерозія та пошкодження поверхні. Для з’ясування причин такої поведінки планується провести подальші дослідження, зокрема, використовуючи інші матеріали в якості аноду. 2022 Article Erosion behaviour of nickel diffusion membranes in conditions of water electrolysis / G.P.
