“…However it was clearly indicated that the hydrolysation and the following concentrating methods have to be much improved to produce higher glucose concentrations in the hydrolysates. It was reported early on that pure glucose in a concentration of 1 M provides current density values from 5 (at RT) to 8 mAcm -2 (at 51 o C) with a voltage of 0.5 V [1,2]. Thus, the detected OCV and current density values with a lower glucose concentration in hydrolysates did not produce values equal to those reached earlier with pure glucose [1,2].…”

“…In this study, an anode catalyst of alloyed platinum with palladium (Pt-Pd) and a combined cathode catalyst of cobalt porphyrin complex (CoTPP) and of spinel (MnCo 2 O 4 ) are tested in the test fuel cell with an alkaline electrolyte. It was reported earlier that several electro catalysts can not work well in near-neutral-state electrolytes (at pH 7.4) because of low electric conductivity values [17].…”

Thus, the detected OCV and current density values with a lower glucose concentration in hydrolysates did not produce values equal to those reached earlier with pure glucose [1,2]. The current density values for pure glucose at RT and at 51 o C were found to be essentially higher than the findings in earlier reports [3][4][5], in which biofuel cells with starch or glucose as a fuel were provided with either a microbial culture and/or a proton-selective membrane.…”

“…The ideal fuel for low-temperature fuel cells in power generation systems would be a directly used fuel in a liquid phase, which allows the fuel to be stored and used more easily than gaseous hydrogen does [1,2]. There are fuel cells which operate with solidphase electrolyte and tissue cultures, which contain a biological electro-catalyst either in the form of enzymes or of living microorganisms, together with proton-selective membranes for the in situ reforming of bioorganic materials [3][4][5].…”

“…However, fuels such as glucose or other carbohydrates can easily be utilised by mixing them directly in the electrolyte without the use of any auxiliary equipment or additional microbial cultures. Many studies have been conducted in which metallic catalysts were used in electrolytes with different pH values [1][2][3][4][5][6][7][8][9][10][11].…”

Abstract. The use of glucose, which is produced from the acid hydrolysis of starch and cellulose, is studied as a fuel in a low-temperature direct-mode fuel cell (LTDMFC) with an alkaline electrolyte. Glucose is regarded as being as good a fuel as bioethanol, because both the fuels give 2 electrons per molecule in the fuel cell without carbonisation problems. However, glucose can be produced with fewer processing stages from starch and cellulose than can bioethanol. In the LTDMFC the fuel and the electrolyte are mixed with each other and the fuel cell is equipped only with metal catalysts. Cellulose as a fuel is of great importance because the fuel for the energy production is not taken from food production. A description of an acid hydrolysis method for starch and cellulose is presented. Values for glucose concentrations in each hydrolysate are analysed by means of a chromatographic method. Each glucose hydrolysate was made alkaline by adding of potassium hydroxide before feed in the fuel cell. Polarisation curves were measured, and they were found to produce lower current density values when compared to earlier tests with pure glucose. The Coulombic efficiency of pure glucose electrochemical oxidation in LTDMFC, which was calculated from a ratio of detected current capacity (As) to the maximum current capacity with the release of two electrons per molecule, was also found to be very low. Concerning the hydrolysates, the glucose concentrations were found to have values that were too low when compared to the earlier tests with pure glucose in a concentration of 1 M. The further development demands for the system under consideration are indicated. The concentration of glucose in the hydrolysate is essential to achieve high enough current density values in the LTDMFC.

The increasing concerns for sustainable economy and alarming environmental health are making researchers to pay serious attention to bio-fuels that too primarily synthesized from the biomass. An energy transforming machine extracting energy directly from biomass would be an idyllic condition. Regrettably, devices using sustainable energy resource have shown to have low output, not meeting the demands of practical appliances. Serious efforts are being dedicated to research on the prospects of bio-fuel powered fuel cells as green energy exchange tool. To comprehend this, scientists are working on the production and expansion biological fuel cell (BFC) which are electro-chemical devices utilizing electro-active bacteria for producing electricity through oxidation. The materials used for electrodes in BFCs, should have conductivity, porosity, biocompatibility, low in cost and recyclability. The materials tested for BFCs are principally metalbased, carbon-based or purposely built advanced materials. The research efforts over the last decade have positioned macro-porous and composite of carbon-based nanostructures with controllable surface and electronic characteristics to be used as a support-matrix for metallic electro catalysts or as proficient non-metallic electro catalysts in BFCs. This review article discusses about the present challenges and future prospects in the field of current progresses in the field of carbon based catalysis system for biomass based microbial fuel cells which extract energy from biomass resources either directly or indirectly.
