Degradation of Materials Under Conditions of Thermochemical Cycles for Hydrogen Production - Part III

Abstract

A capsule method was employed to screen a number of materials for degradation under selected conditions of the sulphur‑iodine (SI) and the copper‑chlorine (Cu‑Cl) thermochemical cycles.  A summary of the results of an experimental investigation is given.  The recommendations for the selection of the materials required for the construction of the electrolyser subsystem of the copper chlorine hybrid cycle are presented and discussed with the associated rationale.  Some remaining uncertainties are illustrated on the basis of the experimental evidence gathered.
