The results indicated that MFCs catalyzed by surface-attached cells and matrix-embedded cells had better chemical oxygen demand (COD) removal and power production efficiencies than those catalyzed by freely-suspended cells.
The performance is defined in terms of wider operating range or stall delay, power production and efficiency.
The analysis has been focused on such parameters as pressure drop of the fixed bed reactor, the inlet air flow, the syngas production, electrical power production and efficiency, looking for improving the performance and guaranteeing the proper system operation.
In a typical running with 4.3 kW stack power, the hydrogen production efficiency, gross power generation efficiency and heat recovery efficiency approach to 76%, 41%and50%0%, respectively.
An approach for comparison of ORC working fluids was proposed based on molecular components, enthalpy versus temperature, thermal efficiency, net power production, and exergy efficiency of ORC.
Based on the thermodynamic-electrochemical analysis, mathematical expressions of some performance parameters such as the cell potential, power output, efficiency, and entropy production rate are derived.
Retrofit strategies for the integration of LNG cold energy have been investigated, and their impacts on power production and system efficiency are systematically compared.
According to the results, de-rating is the worst surge control strategy, both from the point of view of power production and thermal efficiency.
Fuel cells allow for increased efficiency in power production when compared to the thermodynamically limited efficiencies of heat engines.
