Vapor Phase Water Electrolysis or Pocket Mediated Water Electrolysis? [PDF]

Journal of The Electrochemical Society
In this article, we show that adventitious water/electrolyte coming from various processing steps can obscure the assessment of results for a fully vapor-fed water electrolyzer. A couple hundreds of μl per cm2 of water can sustain typical operating current densities of 10 mA cm−2 geo for tens of hours, thereby not reflecting the true ...
