1 security
1.1 The battery contains a highly corrosive sulfuric acid liquid. Keep this product away from children. Users must wear safety glasses and rubber gloves when using the battery. If sulfuric acid splashes on your eyes, skin or clothing, flush with plenty of water. Or go to the hospital in serious circumstances.
1.2 Hydrogen and oxygen are generated when the battery is charged, and it may cause a fire or explosion when the exhaust port is clogged. So batteries should be kept away from fire and prevent short circuits
1.3 The battery surface is made of flammable polypropylene and should be kept away from fire.
2 storage
2.1 This type of battery is a liquid lead-acid battery and should be stored in a dry, clean, well-ventilated place at a temperature of 5-25°C. Avoid direct sunlight and at least 2 meters from the heat source.
2.2 The battery must not be inverted or tipped over. And must avoid any mechanical impact and heavy pressure.
2.3 This series of batteries can be stored at room temperature for 6 months, do not need to charge before use within 6 months. If the battery is stored for more than 6 months. It can be put into use after charging.

How the hydrogen fuel cell demonstrator works
in a fuel cell, chemical energy is converted directly to electricity without having to go through the fuel process.Hydrogen and oxygen come in from the outside, react to form water, which generates electricity and heat.Pure oxygen or air may be used.
PRINCIPLE
Membrane electrode unit is the core part of PEM fuel cell.
The hydrogen is oxidized.
Under the action of an electrode catalyst, such as platinum, hydrogen is broken down into two protons and electrons.H+ ions move to the cathode side through the proton conduction membrane.If the cathode is equipped with an external circuit, electrons flow to the cathode to generate current.The oxygen supplied to the cathode is reduced and the hydrogen proton is combined to form water.
The hydrogen supplied to the anode is oxidized.Catalyzed by an electrode, such as platinum, hydrogen is broken down into protons and electrons.H+ ions move to the cathode side through the proton conduction membrane.If a circuit is provided to the cathode, electrons flow to the cathode, creating a current.The supply of oxygen to the cathode decreases and reacts with protons to form water.
The utility model relates to a hydrogen fuel cell demonstrator, which comprises a hydrogen gas source, an oxygen gas source, a fuel cell and a load.
APPLICATION
The hydrogen fuel cell demonstrator of the utility model is intuitive and vivid. The fuel cell is connected with the oxygen gas source and hydrogen gas source to provide the hydrogen and oxygen needed for the reaction. The power generation of the fuel cell drives the load work, enabling students to intuitively understand the basic structure and working principle of the fuel cell.
