System Approach of a Pressurized High-Temperature Electrolysis

摘要

Sunfire presents an approach for a pressurized SOC system. It is shown how stacks and Hot-BoP components can be operated at elevated pressures. First results of a prototype with a nominal electrolysis DC input power of 10 kW and an operation range of up to 15 bar are shown. Main objectives are the control of the differential pressures between the separate pressure compartments, stack performance and thermal behavior at varying pressure levels.
