Highly Efficient Reversible Protonic Ceramic Electrochemical Cells

The research project jointly develop key technologies for reversible protonic solid oxide electrochemical cells (Re-PSOCs) with Asia Hydrogen Energy Co., Ltd. and Leatec Fine Ceramics Co,. Ltd. The four sub-projects focus on the development of key materials and novel microstructures for Re-PSOCs, cell packaging and process integration, establishment of reversible fuel/electrolysis electrochemical testing platform, and long-term performance analysis for Re-PSOCs. This project will also develop H2O-CO2 co-electrolysis technology to produce high economic value hydrocarbon chemical raw materials and meanwhile, to establish a dynamic physical model of Re-PSOC under wind or solar output power, in order to greatly expand the diversified situation of this technology in energy storage applications, effectively raising renewable energy utilization.The enterprise partner in this project, Asia Hydrogen Energy's development goal is to provide customers with total solutions for hydrogen energy production, storage and application. In addition, Leatec Fine Ceramics is a domestic production plant that produces green energy ceramics (reducing energy consumption and pollution) and energy functional ceramics (producing or converting energy). They can provide specific directions or guides to develop Re-PSOC in terms of product niche. Cooperative enterprises can also strength the company's competitiveness and expand their international market visibility through the long-standing international cooperation network established by the project team (such as Nanyang Technological University and Kyushu University). The overall goal of this integrated project is to develop an electrolyzer system with a continuous operation of 36 hours, a yield of 100 liters H2/day and an overall energy consumption of < 6.0 kWh/m3; and the target efficiency of the core Re-PSOC cell of the system: Faraday efficiency (FE) > 85%, energy conversion efficiency (ECE) > 80%; and its performance degradation rate <5% after 100 hours of long-term stability test.
