A power supply device is provided. The power supply device includes a fuel cell, a hydrogen generator, a check valve and an exhaust valve. The fuel cell has a hydrogen inlet and a hydrogen outlet. The hydrogen generator is connected to the hydrogen inlet and used for generating hydrogen. The check valve is disposed in the hydrogen inlet and used for preventing the hydrogen within the fuel cell from flowing to the hydrogen generator, and preventing exterior air from entering the fuel cell. The exhaust valve is disposed in the hydrogen outlet for exhausting the hydrogen within the fuel cell.

Disclosed is a magnetic catalyst formed by a single or multiple nano metal shells wrapping a carrier, wherein at least one of the metal shells is iron, cobalt, or nickel. The magnetic catalyst with high catalyst efficiency can be applied in a hydrogen supply device, and the device can be connected to a fuel cell. Because the magnetic catalyst can be recycled by a magnet after generating hydrogen, the practicability of the noble metals such as Ru with high catalyst efficiency is dramatically enhanced.

Disclosed is super water absorbent polymers applied to contain water, and the polymers may further collocate with water absorbent cotton materials to accelerate water absorbent rates. The described water absorbent materials are combined with solid hydrogen fuel to complete a stable hydrogen supply device. Performance of the hydrogen supply device is not effected by inverting or tilting thereof. Even if inverting or tilting the device, the water contained in the water absorbent materials does not flow out from the device. As such, the MEA film in the fuel cell connected to the hydrogen supply device will not blocked by the water, thereby avoiding the fuel cell performance degradation even breakdown.

Disclosed is a flexible power supply including a hydrogen supply device connected to a flexible fuel cell, wherein the hydrogen supply device includes a moldable hydrogen fuel. In one embodiment, the flexible fuel cell is a sheet structure, and the hydrogen supply device is a flexible flat bag, wherein the fuel cell and the hydrogen supply device are adhered to complete a sheet of a flexible power supply. The sheet of flexible power supply can be put in the pocket of cloth or baggage, or directly sewn on the outside of cap or overcoat.

Solid-state hydrogen fuel with a polymer matrix and fabrication methods thereof are presented. The solid-state hydrogen fuel includes a polymer matrix, and a crushed mixture of a solid chemical hydride and a solid-state catalyst uniformly dispersed in the polymer matrix. The fabrication method for the solid-state hydrogen fuel includes crushing and mixing a solid chemical hydride and a solid-state catalyst in a crushing/mixing machine, and adding the polymer matrix into the mixture of the solid chemical hydride and the solid-state catalyst to process a flexible solid-state hydrogen fuel. Moreover, various geometric and/or other shapes may be formed and placed into suitable vessels to react with a particular liquid and provide a steady rate of hydrogen release.

The present invention relates to a low-priced bioassay element, comprising: a carrier comprising a porous cellulose filter paper and a stationary layer, wherein said stationary layer comprises casein and calcium ions, and covers on said porous cellulose filter paper; a coating film comprising casein and calcium ions, which covers on the surface of said carrier; and an enzyme dispersed in said coating film; in which the activity of the enzyme comprised in the bioassay element can be maintained for a long time, and the assay result can be read by naked eyes or a spectrophotometer.
摘要:
An electric driven protein immobilizing module and method aims at immobilizing proteins rapidly and steadily on the surface of a selected support. The invention employs the characteristics of proteins/enzymes forming a slightly negative charge in a buffer solution. An external electric field is set up to drive the proteins/enzymes to be adsorbed onto the support. The invention improves upon conventional absorption or bonding methods that fix the protein in a non-directional approach which results in masking the protein active site and subsequently loss the protein activity. Thus activity of the protein/enzyme improved, while the time-consuming problem and enzymatic activity loss problem of incubation and vacuum absorption method may be avoided.
