Abstract

The invention discloses a chlorine-magnesium fuel cell which comprises a cell body, a chlorine storage gasification system and an electrolyte circulation regeneration system. The electrolyte circulation regeneration system comprises a filter, an extraction stirrer, a water purifier, a standing device and an electrolyte storage tank, the electrolyte storage tank is communicated to the outer side ofthe standing device, and a second power pump is mounted in the outer side of the electrolyte storage tank. The cell body comprises a cell casing and a chlorine channel, the cell casing is internallyprovided with a cathode film assembly, the cathode film assembly is internally provided with a magnesium alloy positive plate, and a cell middle axle is fixedly to the inner middle of the cell casing.The chlorine-magnesium fuel cell uses multi-component magnesium alloy with high performance as the anode, the electrochemical conversion rate is high, electrochemical reaction is uniform, and the current and voltage are stable; and chlorine serves as an oxidizing agent, the electrode potential is high, the cost is lower, and the energy density is high.

Description

technical field [0001] The invention relates to the technical field of novel fuel cells, in particular to a magnesium chloride fuel cell. Background technique [0002] Energy is an important material basis for the survival and development of human society. As the most important secondary energy source, electric energy, with the rapid development of economy, the human demand for electric energy is increasing, which also promotes the transformation and upgrading of the electric energy industry. At present, lithium-ion batteries are the most widely used in the market. Due to their advantages such as small self-discharge, high specific capacity, good cycle performance and environmental friendliness, the technology is developing rapidly and the technology is relatively mature. However, the lithium resources on the earth are limited, the cost of lithium-ion batteries is high, the specific energy is too low, and there are safety problems, which cannot meet the requirements of pure...
