Abstract: A direct Fuel Cell is based on organic liquid hydrogen storage materials, and includes a fuel cell unit connected to load through AC/DC convert circuit. The outlet and inlet of hydrogen storage materials on the fuel cell unit is connected to hydrogen storage tank through hydrogen storage output pipe and hydrogen storage input pipe, respectively. There is a pump for hydrogenated hydrogen storage materials on the hydrogenated hydrogen storage materials input pipe; the second outlet for water and gas on the fuel cell unit is connected to water tank through the second water output pipe. The water and gas inlet on the fuel cell unit is connected with oxygen input pipe; there is a gas outlet on the top of the water tank; the hydrogen storage materials tank contains hydrogen storage materials. The mentioned hydrogen storage materials are a multi-component mixture of liquid unsaturated heterocyclic aromatics.

Abstract: The present invention relates to a method for producing europium activated yttrium gadolinium borate phosphors and a product produced by the method. The chemical formula of said phosphors is (Y1-x-y-zEuxGdyMz)BO3, wherein: 0.01?x?0.01, 0?y?0.5, M=Ca, Sr, Ba or Mg, 0?z?0.1. The method comprises: mixing a yttrium source, an europium source, a gadolinium source, a boron source and an M source to produce an aqueous solution in a microwave system; placing the aqueous solution into a microwave system, and making the solution reacting under the condition of condensation cycling and stirring to produce a sol; heating the sol in a microwave system to produce a gel; drying, baking, washing and collecting the gel to produce the product. The method of the present invention can greatly short the production period and improve the production efficiency. The europium activated yttrium gadolinium borate phosphor particles is of a particle size as fine as 80 nm and has good uniformity and emitting performance.
