Description

Power Generation Unit with Silver Cadmium Oxide Hydrogen Storage Bottles

technical field

The invention relates to a new type of energy source, in particular to a solid-state hydrogen battery, in particular to a hydrogen storage device.

Background technique

At present, fuel oil is generally used for the power of automobiles. Due to limited oil resources, people have to seek new alternative energy sources, such as electric energy, solar energy, and the like. As a substitute for motor fuel, there are known liquefied petroleum gas and liquefied natural gas. Cars using these alternatives emit relatively less harmful gases, but still fail to fundamentally solve the problems of energy and pollution.

The application of hydrogen as a fuel has been paid more and more attention, and gaseous hydrogen is very easy to explode. In the field of hydrogen-powered vehicles, hydrogen can be stored in the vehicle's on-board high-pressure tank. Such storage systems are not efficient on a volumetric level and present safety concerns due to storage pressures that are too high, eg, 5,000-10,000 psi (approximately 350-700 Bar) air pressure.

Contents of the invention

In order to achieve the above objectives, the present invention proposes a solid hydrogen power generation device, which uses solid hydrogen as an energy source, converts solid hydrogen into electrical energy, and uses the electrical energy to drive a motor to perform work. The solid-state hydrogen power generation device is equipped with related auxiliary devices, such as hydrogen storage devices, hydrogen supply devices, power generation battery devices, etc., to achieve the purpose of saving fuel and reducing exhaust emissions.

The hydrogen storage device includes a hydrogen storage bottle, and the hydrogen storage bottle contains hydrogen storage particles, which can store the activated hydrogen gas in a solid form, and release the stored hydrogen gas when absorbing heat. The hydrogen storage particle has an interior cavity surrounded by a porous wall. One end of the hydrogen storage bottle is provided with an air hole, and a filter is arranged in the air hole. The filter is made of metal powder sintered or made of stainless steel micro-dense mesh, which can allow hydrogen to flow and filter to prevent other gases and impurities from entering the hydrogen storage bottle. When hydrogen is injected into the hydrogen storage bottle, the hydrogen enters the hydrogen storage bottle through the filter. At this time, the hydrogen storage particles contained in the hydrogen storage bottle quickly absorb the hydrogen gas. After activation, a large number of hydrogen molecules are converted into solid hydrogen and stored in the hydrogen storage tank. Inside the bottle, the hydrogen is no longer stored in the form of high-pressure gas, so as to achieve the purpose of safe storage and transportation.

The hydrogen supply device can release the solid hydrogen stored in the hydrogen storage particles in the form of gaseous hydrogen molecules through the air guide tube at the air hole of the hydrogen storage bottle, and send it to the power generation battery device.

The power generation battery device is similar to the general battery structure, but the materials used are different.

The hydrogen storage technology and power generation device provided by the invention effectively solve a series of problems existing in the gaseous storage mode, fill the gap in this technical field, and are innovative. The hydrogen storage technology and power generation device can be used in various vehicles, and has broad development prospects due to its safety, reliability, short-term high efficiency, economy and convenience, environmental protection and energy saving. The use of solid hydrogen as an energy source can solve the environmental pollution caused by oil emissions, and the use of solid hydrogen as an energy source can reduce costs.
