Abstract: A complex fuel cell stack with hydrogen storage unit is introduced. Through the new configuration of the PEM fuel cell stack, no cooling system and cooling fluid is needed for the fuel cell stack, since hydrogen storage vessel can act as a heat sink to protect the expensive catalyst layer of the MEA of the fuel cell away from over-heated and damaged. In addition, the waste heat generated from the operation of the fuel cells can aid in release of hydrogen from hydrogen storage alloys inside the hydrogen storage vessel.

Abstract: In a method for evaporation depositing uniform thin films, a film is deposited on a substrate of a vacuum environment while maintaining a constant deposition rate. A cover is installed on a wall of the evaporation vessel. When the evaporation material is heated to an evaporation state and the interior of the evaporation vessel reaches a first vapor saturation pressure, the vapor of the evaporation material flows towards a pressure stabilizing chamber. When the pressure stabilizing chamber reaches a second vapor saturation pressure which is smaller than the first vapor saturation pressure, the vacuum environment has a vacuum background pressure which is smaller than the second vapor saturation pressure, so that the evaporation material vapor flows from the pressure stabilizing chamber towards the vacuum environment at constant rate due to the pressure difference, so as to evaporate the substrate.

Abstract: A preparation method of high purity and densified tungsten-titanium metal which mixes titanium metal powder and tungsten metal powder together; adds metallic nitrates (such as nickel nitrate) as combustion improvers; then taking into the account of the characteristics of metal nitrate, which is soluble in alcohols to form a liquidous precursor, adds metal powder to mix together thoroughly, so that the sintering agent is expected to be colloid and uniformly spread among the tungsten-titanium metal powder. The preparation method significantly reduces the ratio of the combustion improver during the preparation of the high purity and densified tungsten-titanium target material.
