... that the maximum energy needs of the building can be met by 12 fuel cell stacks with nominal capacity of 8.5 kW. Annual average electricity cost of thissystem is equal to 0.39 US$/kWh and entropy generation of this system through a year is equal to 1004.54 GJ/K 1 . It is also concluded that increase in ambient...

... more rapidly than the standard potential for the electrochemical oxidation of carbon to CO, which also has a positive slope due to a positive entropy change of the overall reaction. This extra high OCV is an additional argument for developing the DCFC in particular a DCFC at high temperatures in which...

..., for a detailed determination of the temperature profile in the fuel cell solid components, the separate consideration of the cathodic and anodic half-reactions is required. A method for determining the specific entropy change of the half-reactions based on Seebeck-coefficient data is adopted from the literature...

...G. F. Naterer; C. D. Tokarz This article aims to develop an entropy based method of systematically improving efficiency of fuel cells. Entropy production of both electrochemical and thermofluid irreversibilities is formulated based on the Second Law. Ohmic, concentration, and activation...

... to define the principle design rules of sustainable technologies in minimizing the irreversible entropy production. The ideal, but real process chain is defined by a still reversible structure or logic of the process chain—the reversible reference process chain—but consisting of real components...

.... In this analysis, pressure loss in the fuel cell and heat transfer of the cooling channel are taken into account whereas, pressure loss in burner and reformer are neglected. Results show, to minimize the entropy generation, fuel cell temperature must be increased to maximize PEM fuel cell temperature. Also, burner...
