“…The reversible potential is obtained considering its value at the standard conditions ( E 0 ) and using the Nernst equation and:

E = E^{0} + \frac{RT}{nF} \ln ([], \frac{{normalp}_{H_{2}} {((), {normalp}_{O_{2}})}^{0.5}}{p_{H_{2} normalO}})

where,

p_{{normalH}_{2}}

p_{{normalO}_{2}}

, and

p_{H_{2} normalO}

are the partial pressures of hydrogen, oxygen, and water, respectively. The real potential is defined based on the activation ( V act ), concentration ( V con ), and ohmic ( V ohmic ) over‐potentials as follows:

V_{act} = \frac{RT}{αnF} \ln ((), \frac{normali}{i_{0}})

V_{con} = - \frac{RT}{nF} \ln ((), 1 - \frac{i}{{normali}_{normalL}})

SUMMARY In this article, the application of a hybrid phosphoric acid fuel cell and organic Rankine cycle (PAFC/ORC) system was thermo‐economically investigated for sulfuric acid production in Sarcheshmeh copper complex (SCC); the second largest copper deposit worldwide. The electricity that is produced by the system is consumed by electrolyzer to produce the hydrogen and sulfuric acid. Two scenarios were considered for applying the PAFC thermal energy as thermal source of the ORC to produce further power. The performance of the system was investigated considering various important parameters such as organic fluid type, PAFC current density (IPAFC), fuel & air consumption factors as well as the ORC turbine inlet pressure (Pi, ORC). The unit cost of sulfuric acid and the hybrid system simple payback period were obtained as 0.0215$/kg and 3.65 years, respectively.

“…So FCs can be represented as a very good option as a distributed generation, since it has high power density in comparison of battery energy storage system (BESS). The PAFC has been considered as a promising power apparatus since more than one decade because of its low operating temperature, compactness and high efficiency [2]. FCs are used in the stand-alone purposes at residential, hospitals, industries as well as electrical vehicles.…”
