A biocathode was designed by the modification of a carbon nanotube (CNT) gas-diffusion electrode with bilirubin oxidase from Bacillus pumilus, achieving high current densities up to 3 mA cm(-2) for the reduction of O2 from air. A membraneless air-breathing hydrogen biofuel cell was designed by combination of this cathode with a functionalized CNT-based hydrogenase anode.
The startup characteristics of plasmatron reformers with gasoline fuel for the generation of hydrogen rich gas is discussed. A brief set of experiments has been carried out at a single fuel and air flow rate. The air/fuel mixture preparation, especially the implications of the gasoline vaporization, has been modeled using a CFD code.
Direct numerical simulation data obtained from two turbulent, lean hydrogen–air flames propagating in a box are analyzed to explore the influence of combustion-induced thermal expansion on turbulence unburned gas. For this purpose, Helmholtz–Hodge decomposition is applied computed velocity fields. Subsequently, second-order structure functions conditioned reactants sampled divergence-free solen...
