Vapor Phase Water Electrolysis or Pocket Mediated Water Electrolysis?
Journal of The Electrochemical SocietyIn 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 ...

This chapter introduces alkaline water electrolysis for hydrogen production from water splitting, beginning with the basic principles of operation. This is followed by discussion of the types of cell components in general use in commercially available devices. The use of alkaline water electrolysis in industry is discussed, and finally recent trends in

Electrocatalysis in Water Electrolysis
ECS Meeting Abstracts, 2015In a recent publication, generation of active surface sites by the overpotential was described as a common pattern in fuel cell electrocatalytic processes [1]. This paper discusses the applicability of the same pattern to the electrocatalytic processes in the water electrolyzer .

Photoelectrochemical Water Electrolysis
2020Photoelectrochemical (PEC) water splitting is an attractive approach for converting solar energy to chemical fuels, such as hydrogen, and it has been intensively investigated over the past decades. This chapter will present a wide description of the experimental and theoretical aspects that relate to PEC water splitting, including fundamental ...

Theory of the electrolysis of water
Protection of Metals, 2008Based only on simple electrodynamics relations with no use of Arrhenius’ ionic hypothesis, an equation relating the polarization current density to the potential is derived and used in describing the kinetics of electrolysis by an example of water decomposition in a wide range of potentials.

In implementation of the hydrogen economy, the electrolysis of sea water as the source of hydrogen has been discussed. Two options exist for performance of this electrolysis. The first option is to subject the water to total desalinization to remove all impurities and produce essentially distilled water.
