Solid oxide fuel cell system emulation by multi-renewable working fluids for efficient energy conversion

Hydrogen as a primary form of fuel is of crucial importance to achieve global aiming, which requires high efficiency, renewable power generation technologies but facing difficulty on its production and storage. Plenty of hydrogen carriers bring a new horizon for future application but its terminal application technology with high efficiency and demonstration doesn’t appear.<br><br>Solid oxide fuel cell has the natural advantage on multi-fuel selectivity which bring its wide application with different fuel sources and future power generation technology with promising future.

The commercial SOFC system request comprehensive property understanding, diagnosis and system design. The hotbox unit requests the validation for the thermal balance of the SOFC system which integrates with the pre-reformer, SOFC unit, exhaust combustor and heat exchanger. A comprehensive and commercial-aimed model design and simulations are necessary for the SOFC system property understanding of its multi-fuel property.<br><br>In this thesis, a complicated and validated semi-empirical SOFC module has been conducted with multi-function to accurately predict the real working condition for the SOFC system design.
