摘要

This study analyzes the market prospects and technological development pathways for intermediate-temperature solid oxide fuel cells (IT-SOFCs) as a key component of advanced distributed energy systems. The objective is to assess both the global and Russian market for SOFC technology and to evaluate the technical readiness of materials and architectures enabling operation at 600–700 °C. A review of published market data and peer-reviewed literature is combined with experimental results from GIREDMET State Research and Design Institute of Rare Metal Industry, JSC (GIREDMET). The technology is distinguished by high efficiency in converting the chemical energy of fuel into electricity, low CO₂ emissions, and extended service life compared to conventional SOFCs operating above 800 °C. Key findings include: the global SOFC market is projected to grow at a CAGR of 26–32% through 2034; metal-supported IT-SOFC architectures with thin-film LSGM and GDC electrolytes achieve power densities exceeding 0.8 W cm⁻² at 700 °C, representing a technically significant milestone for this architecture class; and rare-earth material expertise at GIREDMET provides a competitive foundation for advancing IT-SOFC development within the national hydrogen economy.
