“…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].…”

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.

[a] 1IntroductionDetermination of glucose has been widely implemented in clinical diagnostics,f ood industry, biotechnology,e tc. [1,2].I nr ecent years,l ots of studies have been conducted to developn ew glucose detection methods with good sensitivity and selectivity.B ased on these requirements,e lectrochemical sensors which include enzymatic and non-enzymatics ensors have been used widely to detect glucose [3].W hereas,s ome drawbackso fe nzymatic sensors are also foundedi ng lucose oxidase-based biosensors such as it is too sensitive to the thermal and chemical information, and high complexity,l ow stability,b ad reproducibility,a nd so on. These disadvantages have affected the application of glucose oxidase-based biosensors greatly [3][4][5].T herefore,alot of studies have been carried out to improve the non-enzymatics ensors with good properties such as low detection limit high sensitivity,f ast response time and wide linear range [6][7][8][9][10][11][12][13].Nowadays,w ith the development of nanotechnology, more and morenanomaterials have been used for electrochemical sensing which improvet he properties of sensors greatly.A mong all the nanomaterials,n anometals such as Ag, Au,P d, Pt, Ni and Pt-Pd, Pt 2 Pd have been applied widely due to their good conductivity,c atalysis and many other properties [14][15][16][17][18][19][20].C ompared with other metals,N i has perfect catalytic property in glucose detectionw hich results in more application in fabrication of glucoses ensors.S o, how to play the catalytic function of Ni asf ar as possible in the processo fg lucose detection is an urgent question to solvew ith the state of the art.In order to solvet he problem, nanocomposites which constituted by metal and metalo xide have been synthesized to fabricate electrochemical sensors.C ombination of metal and metal oxide could improve the properties of electrochemical sensors due to their synergistic effect. Due to their huge specific surface area, excellent chemical stability,l ow cost, and fabrication flexibility,t he metal oxides such as SiO 2 ,C uO 2 ,Z nO,Z rO 2 ,a nd MnO 2 have earned more attention [21][22][23][24][25].A mong these materials, manganese dioxide has been applied in ion exchange,molecular adsorption, biosensor, and energy storage [26].I n addition, owing to its economical and environmentala dvantages [ 27,28],m anganese oxide has also been widely used as the catalysts [29][30][31] in addition to its catalytic activity for carbohydrate,h ydrogen peroxide, ascorbic acid, and oxygen reduction [32][33][34][35][36].Thus,b ased on the good compatibility of MnO 2 and perfect catalytic properties of Ni [37][38][39][40][41][42],M nO 2 nanocompositesa re employed as catalytic supports,a nd Ni/ MnO 2 nanocomposites are synthesized in the research. Then the Ni/MnO 2 nanocomposites have been applied to fabricate glucose non-enzymatic sensor. In addition, an ovel 3D flower like structure of MnO 2 has been obtained in our study,a nd more Ni nanoparticles can be attached on the unique structure of MnO 2 ...
