Overall, the electrodes tested demonstrated the viability of an electrogenerative reactor for thermally efficient ethane dehydrogenation to ethylene over thermal cracking with maximum thermal cracking generating 0.01 mmol/min/cm 2 of ethylene and oxidative dehydrogenation generating 0.1 mmol/min/cm 2 of ethylene. The reactor performance could be further optimized by negating issues around phase separation, electrode densification and electrode-electrolyte reaction.
