“…The specific platinum electrolytes enable the PAFC to work at high temperatures and to remove the hydrogen from the fuel and use that directly from the reformer. 54 Besides, the PAFC operating temperature range is suitable for integration of this technology with the ORCs for power generation or use that as the back up in the power generation technologies. The PAFC electricity efficiency is nearly equal to 40% and this value would be increased to 80% in heat and power cogeneration applications.…”

“…Because of its ability to work with different available fuels, PAFC has become commercially viable and remains the most popular hydrogen/oxygen FC as compared to the other FCs (). The specific platinum electrolytes enable the PAFC to work at high temperatures and to remove the hydrogen from the fuel and use that directly from the reformer . Besides, the PAFC operating temperature range is suitable for integration of this technology with the ORCs for power generation or use that as the back up in the power generation technologies.…”

“…However, ELF/CHP produces more CO 2 emissions as compared to the other scenario. The experimental investigation performed by Wang et al showed that by the combination of the methanol‐reformer with PAFC, the hydrogen production rate is considerably increased (644.8 mL/min/cm 3 , at 180°C) for the low operating temperatures of the system (130‐180°C). The combination of the PAFC with a regenerative electrochemical cycle for low electricity generation rates of 370 to 900 W under the PAFC operation temperatures of 150 to 180°C was investigated by Açıkkalp et al…”

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.

“…Methanol is one of the most favorable liquid fuels for the production of hydrogen due to its low cost, boiling point, and reforming temperature [5]. There are three main ways to obtain hydrogen as an eco-friendly energy carrier, namely, decomposition, steam reforming, and partial oxidation [6,7]. Among these processes, the steam reforming of methanol (SRM) produces higher H 2 /CO 2 ratios and lower CO content in the product.…”

The catalytic properties of hydrotalcite‐based Cu/Zn/Al mixed oxides prepared by the incipient co‐precipitation method, in which various metals were doped through impregnation, were comparatively tested in the steam reforming of methanol (SRM). In addition, the catalysts were characterized in detail by a series of follow‐up surface techniques. Moreover, strong interaction and synergism between Ru and Cu species noticeably promoted methanol conversion and improved catalytic performance. Furthermore, an SRM reaction mechanism is proposed that rationalizes the relationship between copper dispersion on the surface and the size of the copper/oxygen interface where formed intermediates rearrange.

“…It is also considered as the most promising power generation technology in the future 2 . Based on the different conductive ions, FC can be classified as phosphoric acid fuel cells (PAFC), 3 alkaline fuel cell (AFC), 4 molten carbonate fuel cell (MCFC), 5 solid oxide fuel cell (SOFC), 6 and proton‐exchange membrane fuel cell (PEMFC). Because of its simple assembly, low operating temperature, fast start‐up speed, high energy and power density, and utilization of air as oxidant, PEMFC has become the first candidate for both stationary and mobile applications 7,8 .…”

The synergetic effect of air pollutants and metal ions on performance of a 5kWproton‐exchange membrane fuel cell stack

et al. 2020

Summary Large‐scale commercialization of the proton‐exchange membrane fuel cell (PEMFC) is primarily hindered by cost and availability. In the presence of acidic air pollutants, metal ions impact on the durability of PEMFC. This study aimed at determining the effects of metal ions such as Al3+ and Fen+ that originate from the corrosion of aluminum alloy end plate or other metal components, on the performance of a 5 kW PEMFC stack under the synergetic effect of air pollutants. Results obtained from the 500 hours durability test indicated that performance decreased from an initial of 0.682 V to a final 0.623 V at a current density of 1000 mA cm−2. Findings of the energy dispersive spectrometer (EDS) characterization revealed that corrosion was predominant at the air inlet and outlet of the end plate. Metal ions were detected in both the anode and cathode catalyst layer (CL) and proton‐exchange membrane by EDS‐mapping. Compared to the control, it was found that the synergetic effect of metal ions and air pollutants accelerated the degradation of stack performance. This synergetic effect can be mitigated by improving the adsorption performance of filters or avoiding the use of materials with poor corrosion resistance in fuel cell systems.
