    Sammanfattning : Batteries and surrounding structures (e.g. battery modules and packs) in electrical vehicles and devices are often designed in a way that prevents the electro-chemically active part of the battery cells from being exposed to mechanical loads during operation/service. LÄS MER

  3. 22. On Diffusion Transport Properties in Fuel Cell Gas Diffusion Layers Using the Lattice Boltzmann Method

    Författare :Mayken Espinoza Andaluz; Värmeöverföring; []
    Nyckelord :PEFC; lattice Boltzmann method; gas diffusion layers; porosity; Gas-phase tortuosity; permeability; inertial coefficient; diffusibility; pore-scale modeling;

    Sammanfattning : The polymer electrolyte fuel cell (PEFC) is considered as one of the most promising devices for providing efficient, clean and noiseless conversion of chemical energy to electrical energy. This device can provide electrical and thermal energy for transport, mobile and stationary applications ranging in a wide range of power requirements. LÄS MER

  4. 23. Wood-derived lignin-based fibers as supercapacitor electrodes

    Författare :Azega Rajendra Babu Kalai Arasi; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; lignin; green electrode materials; energy storage; supercapacitor;

    Sammanfattning : Today, in order to replace fossil energy sources with renewable energy sources such as solar and wind, reliable energy storage systems that can provide power regardless of the intermittent nature of the energy sources must be created. Especially with the future’s rising energy demands the development of such energy storage systems from green-collar materials with the least negative environmental impact is pressing. LÄS MER

  5. 24. Characteristic Properties and Applications of Fine Particles in Biomass Gasification

    Författare :Azhar Malik; Ergonomi och aerosolteknologi; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Gasification; Biomass; Fine particles; catalyst deactivation; dilution probe sampling; organic;

    Sammanfattning : The gasification of biomass is a promising route to increase the share of renewable sources in the energy mix. Besides having an overall higher thermal efficiency than combustion, it also offers the possibility of producing gaseous and liquid biofuels that can be used in the transport sector. LÄS MER

  7. 25. Reactions on nanostructured and microporous surfaces
