Abstract: A portable fluid delivering system is provided. The system comprises a container, a heat source, a flow rate regulating device and a delivery tube. The container has a containing space for a fluid to be delivered, in a liquid state at room temperature. The heat source provides an elevated vapor pressure in the containing space over the fluid to be delivered, whereby the fluid to be delivered is driven at a desirable rate along the delivery tube.

Abstract: A hydrogen generator essentially composed of a first medium is provided, comprising: a reforming zone, a preheating zone and a heat source. The reforming zone is used for containing a reforming catalyst so as to perform a steam reforming reaction of a hydrogen-producing raw material to generate hydrogen; and the heat source provides heat to the preheating zone and reforming zone, so that the hydrogen-producing raw material is firstly preheated in the preheating zone and then performs the steam reforming reaction in the reforming zone. The reforming zone and preheating zone are divided with a shortest interval of at least about 0.5 mm with the first medium, wherein the first medium has a thermal conductivity (K) of at least about 60 W/m-K.

Abstract: A porous catalyst structure with a high specific surface area comprising a porous substrate with a catalyst layer thereon is provided. The porous catalyst structure can be prepared by a process comprising depositing a metallic layer onto the surface of a porous, metallic substrate by electroplating, and optionally oxidizing the metallic layer into the metal oxide layer. Any conductive porous metallic substrate can be used as the substrate of the subject invention, and the metallic layer may comprise any suitable metal(s) and/or metal oxide(s) with desired catalytic function(s).

Abstract: A process for producing hydrogen is provided. The process comprises the introduction of reactants into a reactor with a steam reforming section containing a steam reforming catalyst to form a hydrogen-containing product. The process is driven by heat generated in a combustion section containing an oxidation catalyst, which comprises a noble metal and boron nitride. According to the process of the subject invention, the first combustion reaction can rapidly generate heat and is advantageous for conducting steam reforming reactions.

Abstract: A method for forming a supported palladium membrane used for hydrogen purification and production is disclosed. The method comprises steps of providing a support, filling the support with a metal, electroless plating a palladium membrane on the support with a palladium salt solution, and DC sputtering a further palladium membrane on the support.
