Alkaline Electrolysis - Introduction and Overview

Abstract

This review describes the principles and history of electrolysis and elucidates the reasons for the development of certain varieties of electrolyzers, namely alkaline electrolyzers, solid polymer electrolyzers, high-temperature electrolyzers, and high-pressure electrolyzers, by outlining the physical and electrochemical basics applying to electrolysis. Materials, design, and operating conditions for alkaline electrolysis are described in further detail, concluding with a brief discussion of the status of electrolysis today. Copyright Stolten, D.
