The Idaho National Laboratory is actively researching the use of solid oxide fuel cells as electrolyzers to produce hydrogen and syngas on a large scale. They have conducted single cell tests, multi-cell stack tests, and multi-stack tests using cells from Ceramatec Inc. and NASA Glenn Research Center. Stack testing included 10 cell and 20 cell stacks up to a 720 cell 15 kW stack. Tests were run for hundreds of hours to over 1000 hours in a bench-scale or new 15 kW integrated laboratory test facility. Results and observations of cell performance degradation will be presented.

Single button cell tests, multi-cell stack, as well as multi-stack testing have been conducted. Button cells from both Ceramatec Inc. (Salt Lake City, UT) as well as from the NASA Glenn Research Center have been tested. Stack testing has concentrated on 10 x 10 cm cells and 20 x 20 cm cells supplied by Ceramatec and ranged from 10 cell short stacks to a 720 cell 15 kW test. Tests were conducted either in a bench-scale test apparatus or in a newly developed Integrated Laboratory Scale (ILS) 15 kW test facility. Tests ranged in duration from 100’s of hours to 1000 hours or more. A description of the Idaho National Laboratory testing facilities and experimental program will be presented, as well as a summary of test results and some observations of cell performance degradation.
