“…The fuel cell systems of Bennetto et al (1983) were cited as the main contributor to the microbial fuel cell design currently used in gastrobotics, the construction of food powered autonomous robots and a robot, 'Gastronome', was presented at the International Conference on Robotics and Applications 2000 (Wilkinson, 2000). The proposed design uses a digestive anode compartment bacterial population, consuming a variety of fuels/foods.…”

This review considers the literature published since 1994 on microbial and enzymatic biofuel cells. Types of biofuel cell are classified according to the nature of the electrode reaction and the nature of the biochemical reactions. The performance of fuel cells is critically reviewed and a variety of possible applications is considered. The current direction of development of biofuel cells is carefully analysed. While considerable chemical development of enzyme electrodes has occurred, relatively little progress has been made towards the engineering development biofuel cells. The limit of performance of biofuel cells is highlighted and suggestions for future research directions are provided.

“…Fuel cells are known to have a very low emission of greenhouse gases such as CO 2 , SO x etc with high efficiencies (70% theoretically and 40~50% practically). Moreover, they are non-polluting energy sources and capable of providing very high energy densities [5][6][7][8][9].…”

Electrochemical performance of pristine carbon supports including graphene nanoplatelets (GNP), graphene oxide (GO) and multi-walled carbon nanotubes (MWCNTs) for catalysing oxygen reduction reaction (ORR) in alkaline media (0.1M KOH) is reported. The reduction potential (least negative) and the peak current densities for the materials follow the order of MWCNTs>GNP>GO, with the performance of pristine MWCNTs (3 mA/cm 2 ) comparable to that of N-and B-dopedMWCNTs. Furthermore, low-loading of platinum nanoparticles on the carbon supports, carried out by microwave-assisted polyol synthesis, led to an increase in the peak reduction current density significantly at lower reduction potentials. Although the same synthesis process was used, the MWCNTs, GO and GNP support samples have different metallic Pt loadings. A comparison of ORR current densities normalized by the mass of Pt loading shows that Pt/MWCNTs have the highest linear sweep voltammetry (LSV) reduction current density of 900A/g, much higher than 510A/g of the commercial Pt-carbon black supports, and is followed by Pt/GNP and Pt/GO which have the LSV value of 500A/g and 200A/g LSV respectively. It is therefore suggested that the Pt/MWCNTs should be given a favourable consideration in ORR for the future development of fuel cell technologies.

“…The potential change that can occur is negligible. The cathode was also included to provide a different potential from the bioreactor mixture and-in addition to the electrons-to accept protons that were transferred along with the electrons in a 1:1 ratio [4]. The simplest imaginable cathode system used in MFCs is the reduction of oxygen to H 2 O catalyzed by a platinum electrode while bubbling air through the cathodic half-cell [26].…”

A microbial fuel-cell type activity sensor integrated into 500 mL and 3.2 L bioreactors was employed for ampero-(lA) and potentiometric (mV) measurements. The aim was to follow the microbial activity during ethanol production by Saccharomyces cerevisiae and to detect the end of carbohydrate consumption. Three different sensor setups were tested to record electrochemical signals produced by the metabolism of glucose and fructose (1:1) online. In a first setup, a reference electrode was used to record the potentiometric values, which rose from 0.26 to 0.5 V in about 10 h during the growth phase. In a second setup, a combination of ampero-and pseudo-potentiometric measurements delivered a maximum voltage of 35 mV. In this arrangement, the pseudo-potentiometric signal changed in a manner that was directly proportional to the amperometric signals, which reached a maximum value of 32 lA. In a third type of arrangement, a reference electrode was added to the anodic bioreactor compartment to carry out ampero-and potentiometric measurements; this is made possible by the high internal resistance of the cultivation. In this case, the reference potential rose to 0.44 V while the current maximum recorded by the working electrodes reached 27 lA. Reference and pseudo-reference electrodes were in all cases K 3 Fe(CN) 6 /carbon. Electrodes were made of 9 cm 2 woven graphite. To compare the electrochemical signals with established values, the metabolism was also monitored for optical density (at 600 nm) indicating biomass production. For fructose and glucose conversion, HPLC with an Aminex column and RI detector was used, and ethanol production was analyzed by GC with methanol as internal standard. The combination of amperometric and potentiometric recordings was found to be an ideal setup and was successfully used in reproducible cultivations.
