Effect of Mesopores of Marimo Nano Carbon Anode Material on Power Generation Performance of Direct Glucose Fuel Cell

Abstract

Direct Glucose Fuel Cell (DGFC) is attracting attention as a clean and sustainable energy source because glucose is the most organic substance in nature. In this study, the effect of the mesopores of marimo nano carbon (MNC) on power generation performance for anode material of 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 supported metal. Also, Vulcan XC-72 which is carbon black of microporous material was used as a comparative material. In the glucose fuel cell performance test, MNC having many pores of about 35 nm showed the highest maximum output density of 0.72 mW cm-2 at 5 wt% metal loading and 0.3 M Glucose. Vulcan XC-72, which was a microporous material had low power generation performance. MNC showed higher power generation performance than that of Vulcan XC-72. The pores of about 35 nm probably promoted ion diffusion and rapid mass transport of reactants and products. These results indicated that MNC was an effective material as anode material for DGFC.
