“…Andersen et al developed a Pt/CNT (20 wt % Pt) anode and obtained a peak power density of approximately 175 mW/cm 2 at 70 °C . An anode catalyst with a low Pt catalyst loading, Ni 59 Nb 40 Pt 0.6 CO 0.4 exhibited a peak power density of approximately 240 mW/cm 2 at 80 °C . Although, in this study the Pt@NiMnCo catalyst had slow reaction kinetics and a relatively high activation potential compared to commercial Pt/C, it can be subjected to be an alternative catalyst for the hydrogen oxidation reaction because of its cost‐effectiveness.…”

“…The TEM images in Figure 3 (c) and (d) demonstrate that the Pt nanoparticles had an average particle size of 3.5 nm and were uniformly dispersed on the surface of the NiMnCo nanoneedles. 19 Furthermore, the elemental compositions of Pt@NiMnCo was confirmed using EDX, as shown in Figure 3 22 An anode catalyst with a low Pt catalyst loading, Ni 59 Nb 40 Pt 0.6 CO 0.4 exhibited a peak power density of approximately 240 mW/cm 2 at 80 C. 23 Although, in this study the Pt@NiMnCo catalyst had slow reaction kinetics and a relatively high activation potential compared to commercial Pt/C, it can be subjected to be an alternative catalyst for the hydrogen oxidation reaction because of its cost-effectiveness. 19 Furthermore, the elemental compositions of Pt@NiMnCo was confirmed using EDX, as shown in Figure 3 22 An anode catalyst with a low Pt catalyst loading, Ni 59 Nb 40 Pt 0.6 CO 0.4 exhibited a peak power density of approximately 240 mW/cm 2 at 80 C. 23 Although, in this study the Pt@NiMnCo catalyst had slow reaction kinetics and a relatively high activation potential compared to commercial Pt/C, it can be subjected to be an alternative catalyst for the hydrogen oxidation reaction because of its cost-effectiveness.…”

“…In recent years, many electrocatalysts such as Pt-based bimetallic electrocatalysts [4][5][6][7][8][9], tri-metallic electrocatalysts [10][11][12] and multi-metallic electrocatalysts [13] have been investigated by many investigators. However, most of preparation methods are too complicated to satisfy the requirement of mass production.…”

“…Nevertheless, Pt/C electrocatalysts that have higher manufacturing costs as well as severe particle agglomerations, 7,8 which decrease its performance, cannot be utilized for industrial and commercial applications. Accordingly, fabricating novel Pt-based alloy catalysts [9][10][11] with lower Pt consumption and higher electrocatalytic activity is the main research focus for modern fuel cells.…”
