Technical and Economic Evaluation of a Formic Acid/Hydrogen Peroxide Fuel Cell System With Pt-M/C as Anode Catalyst

Abstract

Cell performance of formic acid/hydrogen peroxide (HCOOH/H2O2) fuel cell, using commercial Pt-Ru/C, and prepared Pt-M/C (M = Ir, Mo, Co, Ag, W, Ni, Sn) bimetallic catalysts as anode catalysts are experimentally investigated and reported in this paper. Corresponding to cell performance, electrocatalytic activity of the system using commercially available and prepared catalysts is evaluated by linear sweep voltammetry technique (LSV). The result shows that the system using 20%Pt-10%Sn/C yields better formic acid oxidation reaction than that of other Pt-M/C bimetallic catalysts, but it is inferior to that of 20%Pt-10%Ru/C commercial catalyst. In addition, the cell performance of HCOOH/H2O2 fuel cell with various catalyst compositions of Pt and Sn content, in portions of 10:20, 15:15, and 20:10, respectively, is also studied. Comparison among those catalysts, 15%Pt-15%Sn/C yields better cell performance than the others. Levelized energy cost (LEC) and sensitivity analysis on LEC are also assessed.

“…[ 115 ] Further, research on a formic acid/hydrogen peroxide (HCOOH/H 2 O 2 ) fuel cell emphasized the superior formic acid oxidation reaction of the 20% Pt‐10%Sn/C system. [ 116 ] Lastly, a study on an alkaline aluminium hydrogen peroxide semi‐fuel cell demonstrated its capability to power the autonomous underwater vehicle for extended underwater surveys. [ 117 ] Briefly touching upon other notable studies, research on Pt‐Cu bimetallic nanoparticles showcased the Pt50Cu50/C catalyst's superior catalytic activity in direct borohydride‐H 2 O 2 FCs (DBHFCs).…”

“…4 For these reasons, much effort has been devoted to the development of hydrogen peroxide-based fuel cells. [5][6][7][8][9][10][11][12][13] However, there are three issues associated with the direct reduction of hydrogen peroxide in fuel cells. First, the actual cathode potential (0.8 V to 0.9 V vs. SHE) is much lower than the theoretical one (1.78 V vs. SHE), which is mainly attributed to the mixed potential resulting from the simultaneous hydrogen peroxide oxidation reaction (HPOR) on the cathode.…”
