Transfer phenomena in an electrochemical reactor based on mixed oxide conductor

Operation of an electrochemical reactor (ECR) for hydrogen production from steam based on the membrane having mixed oxygen ion and electronic conducti vity has been considered. On the basis of the described model, one can obta in the dependence of the ECR productivity on the anode and cathode gases pa rameters as well as the distributions of EMF, membrane conductivity and cur rent density over the electrochemical section of the ECR. The results for t he ECR based on the CaTi0.8Fe0.2Oy membrane are presented. (C) 2000 Elsevie r Science B.V. All rights reserved.
