Mohawk Innovative Technology, Inc. will develop an ultra-high temperature oil-free anode recycle blower (UHT-RCB) capable of using uncooled SOFC exhaust gas directly at temperatures to 700°C. The objectives of the work are to demonstrate successful operation of a UHT-RCB at relevant anode off-gas temperatures; and determine areas in which performance margin vs. cost tradeoffs can be made to the design of the first prototype to achieve a commercial cost target under $110 per SOFC kWe. The development of a UHT-RCB will potentially overcome the current limitation of gas-driven ejectors in cost and performance penalties while also addressing the need for a high-temperature (700°C capable) recycle blower to increase overall SOFC efficiency by eliminating the need for an external water supply. An additional outcome is system simplification and increased reliability via elimination of the anode off gas cooling system with its required heat exchanger, flow control valves, and system software needed to manage and control cooling gas output.
