Novel design of a compacted micro-structured air-breathing PEM fuel cell as a power source for mobile phones

Novel design of a compacted micro-structured air-breathing PEM fuel cell as a power source for mobile phones
AbstractThe presence of microelectromechanical system (MEMS) technology makes it possible to manufacturethe miniaturized fuel cell systems for application in portable electronic devices. The majority of researchon micro-scale fuel cells is aimed at micro-power applications. There are many new miniaturizedapplications which can only be realized if a higher energy density power source is available compared tobutton cells and other small batteries. In small-scale applications, the fuel cell should be exceptionallysmall and have highest energy density. One way to achieve these requirements is to reduce the thicknessof the cell (compacted-design) for increasing the volumetric power density of a fuel cell power supply.A novel, simple to construct, air-breathing micro-structured PEM fuel cell which work in still or slowlymoving air has been developed. The novel geometry enables optimum air access to the cathode withoutthe need for pumps, fans or similar devices. In addition, the new design can achieve much higher activearea to volume ratios, and hence higher volumetric power densities. Three-dimensional, multi-phase,non-isothermal CFD model of this novel design has been developed. This comprehensive model accountfor the major transport phenomena in an air-breathing micro-structured PEM fuel cell: convective anddiffusive heat and mass transfer, electrode kinetics, transport and phase-change mechanism of water, andpotential fields. The model is shown to understand the many interacting, complex electrochemical, andtransport phenomena that cannot be studied experimentally. Fully three-dimensional results of thespecies profiles, temperature distribution, potential distribution, and local current density distribution arepresented and analyzed with a focus on the physical insight and fundamental understanding. They canprovide a solid basis for optimizing the geometry of the PEM micro fuel cell stack running with a passivemode. . within passive air-breathing fuel cells. Rajani and Kolar [3] developed a single-phase two-dimensional model for a planar air-breathing PEM fuel cell that considered. is mass transfer: for evaporation ( evapphase mm && = ) and for condensation ( condphase mm && = ) (kg/s). So that the mass balance equations

Assessment of pretreatments and enzymatic hydrolysis of wheat straw as a sugar source for bioprocess industry

Assessment of pretreatments and enzymatic hydrolysis of wheat straw as a sugar source for bioprocess industry
Environmental concerns and rising oil prices have led to development of biofuels from crop residuelignocelluloses, among which wheat straw is an important feedstock used in leading commercialbioethanol processes. Lignocellulose is structured in a way that makes direct bioconversion of biomassinto sugars by hydrolytic enzymes difficult and unfeasible, requiring a pretreatment step. Commonbiomass pretreatment technologies are assessed for potential application in obtaining fermentable sugarsof wheat straw. Current outlook, challenges and opportunities on enzymatic hydrolysis of lignocelluloseare also presented . methods is reported in [ 104] .
