Enzymatic fuel cells produce electrical power by oxidation of renewable energy sources. An enzymatic glucose biofuel cell uses glucose as fuel and enzymes as biocatalyst, to convert biochemical energy into electrical energy. The applications which need low electrical voltages and low currents have much of the interest in developing enzymatic fuel cells. An analytical modelling of an enzymatic f...

High-Performance Alkaline Direct Methanol Fuel Cell using a Nitrogen-Postdoped Anode Report Title A commercial PtRu/C catalyst postdoped with nitrogen demonstrates a significantly higher performance (?10–20?% improvement) in the anode of an alkaline direct methanol fuel cell than an unmodified commercial PtRu/C catalyst control. The enhanced performance shown herein is attributed at least parti...

The paper focuses on the conductivity of the fuel cell electrolyte in a membraneless glucose-fueled alkaline fuel cell. The electrolyte conductivity is interpreted using simple physical models, considering either the empirical behavior of the solution’s viscosity, or the consideration of ions and molecules colliding in solutions. The conductivity is expressed as a function of KOH and glucose co...

Glucose is an ideal fuel for fuel cells because it is abundant in nature, renewable, non-toxic and easy to produce. Glucose fuel cells using enzymes and microbes as the catalysts are limited by their very poor performance and rather short durability. In this work, a direct oxidation glucose fuel cell using an anionexchange membrane and three-dimensional structural Au/Ni foam electrodes is devel...

This paper reports on a single alkaline exchange membrane direct formate fuel cell (AEM DFFC) consisting of a carbon-supported palladium catalyst at the anode, a quaternized polysulfone membrane, and a non-precious Fe–Co catalyst at the cathode. It is demonstrated that the AEM DFFC yields a peak power density of 130 mW cm 2 with 5 M potassium formate (HCOOK) at 80 C. It is further shown that wi...

Recently, increasingly attentions have been paid to the electro-oxidation of ethanol in alkaline media in the context of using ethanol as a fuel in anion-exchange membrane fuel cell. Alkaline media presents several advantages compared to acidic media. It has been found that the electrocatalytic activity for etanol oxidation in alkaline media is much higher than that in acidic media [1]. Further...

In this study, 3D-structured NiMo coatings have been constructed via the widely used electrodeposition method on a Ti surface and decorated with very small Au crystallites by galvanic displacement (Au(NiMo)/Ti). The catalysts characterized using scanning electron microscopy, energy dispersive X-ray analysis, inductively coupled plasma optical emission spectroscopy. Different Au(NiMo)/Ti catalys...

The design, fabrication and characterization of an inorganic catalyst based direct glucose fuel cell using mesoporous silica coating as a functional membrane is reported. The desired use of mesoporous silica based direct glucose fuel cell is for a blood vessel implantable device. Blood vessel implantable direct glucose fuel cells have access to higher continuous glucose concentrations. However,...
