System Relevant Redox Cycling in SOFC Stacks

Abstract

staxera GmbH is a manufacturer of commercial available solid oxide fuel cell (SOFC) stacks and Integrated Stack Modules (ISM). The aim of development and testing is to meet the requirements of existing customers and the needs of the market. Besides high power densities, low degradation rates in long term operation and thermal cycling capability, the possibility for oxidation and reduction (redox) cycles as a requirement of system operation or in case of a system failure is a big challenge in today's SOFC stack development. In this publication, data for different types of redox cycles at stack level is reported, including system relevant combined thermal and redox cycling.
