Abstract

Abstract: In this study, the effect of mesopores in the Marimo nanocarbon (MNC) anode material on the power generation performance of a direct glucose fuel cell was investigated. Three types of MNC with different mesopore distributions were used for the catalyst support material; Pt was used as the loaded metal. In the glucose fuel cell performance test, MNC containing many pores of approximately 35 nm showed the highest maximum output density of 0.72 mW cm −2 at 5 wt% metal loading and 0.3 M Glucose aqueous solution. The pores of approximately 30 nm may promote ion diffusion and rapid mass transport of reactants and products. These results indicated that MNC was an effective anode material for the direct glucose fuel cell. Graphical abstract: Image, graphical abstract
