a hydrogen battery

Abstract

A hydrogen cell comprises an alcohol evaporation device, a hydrogen production device and a fuel cell which are connected through pipelines. The hydrogen cell is characterized in that the alcohol evaporation device comprises an evaporator, the evaporator comprises a body, multiple rows of round pipes are arranged in the body, heating catalytic agents are placed in the round pipes, multiple micropores are formed in peripheries of the round pipes and filled with steel balls, liquid alcohol flows through the micropores and is evaporated due to heat released by the heating catalytic agents to form gaseous alcohol, and the operating temperature of the alcohol evaporation device is in a range of 68-180 DEG C. The hydrogen production device reforms the gaseous alcohol by the aid of a reformer and then provides a hydrogen source for the fuel cell. The fuel cell comprises a fuel cell stack and an inverter, and a storage cell is connected between the fuel cell stack and the inverter.

Description

technical field [0001] The invention belongs to the technical field of new energy, and in particular relates to a hydrogen battery. Background technique [0002] Proton Exchange Membrane Fuel Cell (PEMFC, Proton Exchange Membrane Fuel Cell) technology is a technology that can convert hydrogen and oxygen in the air into clean water and release electricity. The hydrogen reaches the anode through the pipeline or the gas guide plate, and the anode catalyst Under the action, hydrogen molecules dissociate into positively charged hydrogen ions (ie protons) and release negatively charged electrons. Hydrogen ions pass through the electrolyte (proton exchange membrane) to the cathode; electrons pass through an external circuit to the cathode. The electrons form a current in the external circuit, and can output electric energy to the load through proper connection. At the other end of the battery, oxygen (or air) reaches the cathode through pipes or gas guide plates; under the action...

Problems solved by technology

In addition, it is difficult to sensitively control the feed amount of methanol vapor by directly heating all the methanol fuel in the container

When it is necessary to change the feed amount of methanol fuel to adjust the intensity of the flame, it is difficult to control it as desired

Moreover, the direct heating method directly contacts the electric heater with methanol. Once the insulator of the electric heating equipment is damaged, there will be a safety hazard.

When the heating is stopped, all the methanol in the container is still maintained at the boiling temperature, and continues to evaporate and keep warm, resulting in a waste of energy

The indirect heating method relies on the heating of the water bath. On the one hand, the evaporation temperature and speed cannot be adjusted sensitively. On the other hand, when the heating is stopped, the temperature of the water bath remains at a high temperature, which makes it difficult to immediately cool down and causes greater energy waste.
