System Design and New Materials for Reversible, Solid-Oxide, High Temperature Steam Electrolysis

PDF Version Also Available for Download.

Description

High temperature solid oxide electrolysis cells (SOECs) offer high electrical efficiency and a potential path to large scale hydrogen production. Solid oxide technology is capable of both power generation and hydrogen production. That makes it possible for the development of a reversible solid-oxide system that can respond to market conditions to produce electricity or hydrogen on demand. New high-temperature electrolyzer cell materials are needed to enable cost-effective hydrogen production system designs based on reversible steam electrolysis. Two test methods were established for the eventual development of the reversible, durable electrode materials: the button cell test and the oxygen electrode test. ... continued below

Description

High temperature solid oxide electrolysis cells (SOECs) offer high electrical efficiency and a potential path to large scale hydrogen production. Solid oxide technology is capable of both power generation and hydrogen production. That makes it possible for the development of a reversible solid-oxide system that can respond to market conditions to produce electricity or hydrogen on demand. New high-temperature electrolyzer cell materials are needed to enable cost-effective hydrogen production system designs based on reversible steam electrolysis. Two test methods were established for the eventual development of the reversible, durable electrode materials: the button cell test and the oxygen electrode test. The button cell test is capable of evaluating the performance and degradation of full solid oxide cells with dual atmosphere of air and hydrogen-steam. The oxygen electrode test is capable of isolating the performance and degradation of the oxygen electrode. It has higher throughput and sensitivity than the button cell test.
