    Fuel Cell Power Conditioning for Low Power Applications

    By Dileep Kumar, H. A. Mangalvedekar, S. K. Mahajan

    Abstract: Fuel Cells are the important building blocks of hydrogen-based applications. Proton Exchange Membrane Fuel Cell (PEMFCs) are useful for ambient temperature operating conditions. Fuel Cells cannot be interfaced to loads directly owing to many sources of power losses. Power Conditioning and Interface are equally important for driving loads using Fuel Cell generated power. Paper discusses the requirements of power conditioning, types of DC–DC converters, Experimental work performed on DC–DC converter …

    Kinetic Studies of Pristine and Nanonickel Catalyzed Ammonia Borane

    By Dileep Kumar, H.A. Mangalvedekar, S.K. Mahajan, A.C. Gangal

    Abstract: The high hydrogen content chemical hydride, Ammonia Borane (NH3BH3, AB) is considered in its pure and catalyzed form for decomposition kinetics. The thermodynamics and slow kinetics are the major issues in addition to potential damage the material likely to cause to the fuel cell. The ability of AB for faster dehydrogenation at lower temperatures with Nickel in its nanoform is explored. The release kinetics, activation energy is computed using Kissinger …
