Modification optimization of risk husk ash bio-filler in sulfonated polyimide membrane for direct methanol fuel cell

Abstract

Direct methanol fuel cell (DMFC) is a very high potential renewable and sustainable energy for portable devices as it in improved performance of the DMFC rice husk ash (SPI/sRHA RHA had been synthesized via the mixing reaction between rice husk ash (RHA) physicochemical properties of the composite membranes produced was carried out using response surface methodology (RSM) (BET) performances of DMFCs too. The optimized membrane (S-12-sR) showed enhanced physicochemical performance as well as the passive single cell performance as compared to pure SPI proton conductivity and IEC that had been achieved by the optimized membrane were 90.97%, 0.1891 S cm−1 and 0.2608 mmol g−1 respectively. The maximum power density of the passive DMFC was improved from 8.1 mW cm−2 to 16.4 mW cm−2 under ambient conditions.
