| dc.description.abstract | In-Situ Resource Utilization (ISRU) can reduce the mass launched to low Earth orbit for a Mars Sample Return Mission by as much as 75%. Solid Oxide Electrolysis is a candidate technology for producing oxygen out of carbon dioxide. A testbed was developed to test the effect of electrode structure on electrode performance. The testbed used all metal interconnects. Electrodes of 0.5 microns (applied by evaporative deposition) and 10-12 microns thick (applied by airbrushing) were produced. The disks were tested in argon, oxygen, and carbon dioxide. The thin electrode showed deterioration in both short term and long term tests. The thick electrode showed no deterioration even over a 120 hour test. Oxygen was produced from carbon dioxide for extended durations. The experiments show the thicker electrode is needed for an oxygen production system. The electrode/electrolyte disks withstood normal handling without damage. | |
