Abstract :
A MW-class, commercial prototype Westinghouse tubular solid oxide fuel cell (SOFC) power plant is being developed for demonstration by the end of this decade. A 5 MW integrated SOFC/combustion turbine power plant design for distributed power applications is shown which can achieve an efficiency approaching 70%. The recent SOFC technology development advancements supporting the commercial prototype are summarized including the successful scale-up to commercial size of the tubular air electrode supported (AES) cell, performance at both atmospheric and pressurized operating conditions of AES cells, cell lifetime and simplified cell manufacturing processes. Recent operational experience with 25 kW AES-SOFC systems and features of the 100 kW SOFC system that is currently in production using commercial size tubular AES cells are described
