Embodiment 1

[0025] A portable power source (see figure 1 and figure 2 ), including micro-fuel cells, control systems, hydrogen production systems and power enclosures; control systems include energy storage batteries and power supply line controllers; hydrogen production systems include water storage tanks, micro pumps and hydrogen production reactors; water storage tanks and The hydrogen reactor is placed side by side at the bottom of the power supply housing, and the micro fuel cell, energy storage battery, power supply line controller and micro pump are placed side by side directly above the water storage tank; the fuel cell is connected to the power supply line controller, and the power supply line controller is connected to the energy storage battery And the micropump solves the problem of starting the portable power supply micropump, and at the same time, the excess electric energy generated by the fuel cell can be stored in the energy storage battery; the micropump connects the ou...

Embodiment 2

[0027] Embodiment 1 The hydrogen production method of the hydrogen production device, the aluminum alloy (or aluminum / sodium borohydride mixture) is pre-stored in the hydrogen production generator, the energy storage battery provides the starting power of the portable power supply micropump, and the reactant water is transferred from the water storage tank It is injected into the hydrogen production reactor through the water inlet pipe, and the solid fuel reacts with water to generate hydrogen; the hydrogen enters the fuel cell through the separation membrane, pressure regulating valve, stainless steel tube and hydrogen flow meter; the fuel cell generates electricity and supplies it to users. Set the water inlet pressure of the micropump to 0.5MPa, adjust the hydrogen pressure of the hydrogen control reactor, the hydrogen delivery is stable, and the portable power supply works well.

Embodiment 3

[0029] The water inlet pressure of the micropump is set to 1MPa, and the rest is the same as that in Embodiment 2. The hydrogen gas is delivered stably, and the portable power supply works well.

Abstract

The invention relates to a safe and controllable portable power supply and a control method thereof, belonging to the field of portable power supply; and aims to provide a portable power supply with high power and high specific capacity. The portable power supply comprises a micro fuel cell, a control system, a hydrogen producing system and a power supply shell, wherein the control system comprises an energy storage cell and a power supply wire controller; the hydrogen producing system comprises a water storage tank, a micro pump and a hydrogen producing reactor, the water storage tank is communicated with the bottom of the hydrogen producing reactor; the fuel cell is connected with the power supply wire controller; the power supply wire controller is connected with the energy storage cell and the micro pump; the micro pump is connected with an outlet of the water storage tank and a water inlet of the hydrogen producing reactor through stainless steel tubes; and a hydrogen outlet of the hydrogen producing reactor is connected with a hydrogen inlet of the fuel cell. When the portable power supply works, the energy storage cell firstly starts the micro pump, water is injected into the hydrogen producing reactor and is subjected to react with solid fuel to produce hydrogen, hydrogen is delivered to the fuel cell to produce electric energy, then the electric energy is supplied to a user, the micro pump, or the energy storage cell through the power supply wire controller. By setting water inlet pressure of the micro pump to be 0.5-1MPa and by controlling hydrogen production rate during hydrolysis of solid fuel of the hydrogen producing reactor, the problem in high heat release during the hydrolysis of the solid fuel of the hydrogen producing reactor is effectively solved through the water storage tank. The portable power supply has the advantages of reliability, good controllability, stable output of electric energy, etc.

Description

technical field [0001] The invention belongs to the field of portable power supplies, in particular to a hydrogen generator suitable for portable fuel cells and a control method thereof. Background technique [0002] With the rapid development of smaller, lighter and higher-performance electronic and communication equipment, portable power supplies, which are indispensable for electronic and communication equipment, have increasingly higher requirements for their performance, especially in terms of power and specific capacity. At present, most portable electronic products use lithium-ion batteries, but the development of energy density of lithium-ion batteries is close to the theoretical limit. Compared with fuel cells, there is still a lot of room for energy density development. In addition, fuel cells do not need slow charging time. . Therefore, vigorously developing fuel cell portable power sources has a good market prospect. In addition to the requirements of small siz...
