📄 Abstract（原文）
When the operating temperature of a Solid Oxide Electrolysis Cell (SOEC) is lower than the outlet temperature of a nuclear reactor, the reactor can be directly coupled with the SOEC as a high-temperature heat source. However, the key to the efficiency and return on investment of this hybrid energy system lies in the expected lifetime of the SOEC. This study assessed Ni-YSZ|YSZ|GDC|LSC fuel electrode support cells’ long-term stability during electrolysis at 650 oC with a current density of -0....
