Acid-treated cells produce about 200% more hydrogen – pv magazine International

US scientists have improved the performance of intermediate-temperature electrolyzers based on protonic ceramic electrochemical cells. Germany and India have signed a hydrogen cooperation deal, while ArcelorMittal has tested the use of green hydrogen in the production of direct reduced iron at a steel plant in Canada. May 3, 2022 Sergio MatalucciThe application of acid for 10 minutes on the top of an electrolyte made of barium, cerium, and zirconium can etch grooves into the surface and remove segregating elements, improving the performance of intermediate-temperature electrolyzers based on protonic ceramic electrochemical cells. Scientists from the Massachusetts Institute of Technology (MIT) have applied the process to address the low proton conductivity of cells. “Their acid-treated cells produced about 200% more hydrogen per area at 1.5 V at 600 C than did any previous cell of…
