“…The active sites of the electrocatalyst get decreased due to agglomeration of the anode electrocatalyst at a very high loading of 1.25 mg/cm 2 within the anode electrode structure. [ 56 ] Thus, the interaction between fuel gas H 2 and the electrocatalyst also decreases. This resulted in a low power density at a very high anode loading of 1.25 mg/cm 2 .…”

Highly efficient and low-cost Pt-Co/C AB bimetallic cathode electrocatalysts were synthesized for hydrogen-based proton exchange membrane fuel cell (PEMFC) using three different types of solvent, namely, dimethyl sulphoxide (DMSO), dimethylformamide (DMF), and ethylene glycol (EG). The physical characterization of synthesized cathode electrocatalysts Pt-Co/C AB -DMSO, Pt-Co/C AB -DMF and Pt-Co/C AB -EG was performed by scanning electron microscope-energy-dispersive X-ray (SEM-EDX), X-ray diffraction (XRD), and transmission electron microscopy (TEM) techniques, whereas the electrochemical investigation of all three Pt-Co/C AB electrocatalysts was performed by CV and EIS studies. The synthesized Pt-Co/C-EG electrocatalyst produced the highest power density of 19.61 mW/cm 2 at a room temperature of 33 C. The power density increased to 26.11 mW/cm 2 , that is, 133%, when the cell operating temperature was raised from 33 to 70 C. The excellent performance of the Pt-Co/C AB -EG cathode electrode proves that it can be recommended as a commercial electrocatalyst for PEMFC cathode. In addition, the EG/EG was identified as the best solvent for the synthesis of Pt-Co/C AB cathode electrocatalysts.

Aqueous Aluminum‐air batteries (AABs) hold promise for advancing high‐energy density storage systems in future technologies. However, their widespread practical deployment is limited by the inherent hydrogen side reactions in Aluminum (Al) and incomplete cathodic reactions. To address these challenges, the Al‐sodium persulfate (Na2S2O8) system is introduced as an alternative to traditional AABs. Utilizing Na2S2O8 allows to simultaneously achieve three critical objectives, namely, eliminating the need for a cathode catalyst, increasing the system voltage from 1.4 to 2 V, and reducing the hydrogen evolution reaction (HER). Three distinct configurations of the Aluminum electrochemical energy system (Al‐EES) using Na2S2O8: static, flow, and gel are developed. The static configuration demonstrates a performance 1.7 times superior to that of traditional AABs. The flow configuration of Al‐EES achieves a discharge duration of 77 h, which is three to four times longer than that of AABs and exhibits an energy density of 2,650 Wh kgAl−1. This emerging technology has the potential to significantly enhance electric vehicles by providing powerful, efficient, cost‐effective, and durable power‐generation devices.

In the present study, low cost platinum based bimetallic electrocatalyst Pt‐Ni/CAB with varying Pt to Ni atomic ratios 3:1, 1:1, and 1:3 were successfully synthesized for oxygen reduction reaction (ORR) of the developed proton exchange membrane fuel cell (PEMFC). The solvothermal process was adopted for the synthesis of Pt‐Ni(3:1)/CAB, Pt‐Ni(1:1)/CAB, and Pt‐Ni(1:3)/CAB using dimethyl sulfoxide (DMSO) as solvent at a temperature of 190°C which is very close to the boiling point. The Pt‐Ni/CAB exhibited the highest activity for the ORR in half‐cell and single cell PEMFC performance. The electrocatalysts Pt‐Ni(1:3)/CAB appeared with smallest crystalline FCC structures having crystallite size of 8.33 nm. The transmission electron microscopy (TEM) analysis also show that the Pt‐Ni(1:3)/CAB has smallest particle size of 1.67 ± 0.45 nm. The cyclic voltammetry (CV) analysis shows Pt‐Ni(1:3)/CAB electrocatalyst offers less activation loss at ORR peak at a potential of 0.16 V as compared to Pt‐Ni(3:1)/CAB (ORR peak – 0.12) and Pt‐Ni(1:1)/CAB (ORR peak – 0.11). The synthesized Pt‐Ni(1:3)/CAB produced a maximum power density of 18.86 mW/cm2 at a maximum current density of 44.8 mA/cm2 with an open‐circuit voltage of 0.914 V at a room temperature of 33°C. The power density improved around 1.34 times when the cell temperature was raised from 33 to 70°C. The Pt‐Ni(1:3)/CAB cathode electrocatalyst could be used as economical to substitute costly commercial pure platinum based electrocatalyst.
