Heat pipe metal bipolar plate air-cooled (single) battery stack, vehicle and electronic device

Abstract

The invention discloses a heat pipe metal bipolar plate air-cooled (single) battery stack, a vehicle and an electronic device. The heat pipe metal bipolar plate comprises a power generation zone and aheat dissipation zone. Communicated sealed spaces are in the power generation zone and the heat dissipation zone and used for phase change heat transfer of a heat transfer medium. The selection of the heat transfer medium can be correspondingly selected according to different application environments. A heat pipe bipolar plate is stored in a sealed space inside the power generation zone in the form of a liquid or solid medium when the heat pipe bipolar plate does not work. A fuel cell works and generates heat energy. A liquid or solid heat transfer medium absorbs heat, is gasified and comes into the sealed space inside the heat dissipation zone. After low temperature air is encountered in the heat dissipation zone, the gaseous heat transfer medium gives out heat and flows back to the sealed space inside the power generation zone to continue to absorb heat, thereby transmitting heat to the power generation zone. A fuel cell stack composed of the heat pipe bipolar plate and a membrane electrode can directly solve the problem of heat dissipation through air cooling. The water cooling system of a fuel cell system is simplified.

Description

technical field [0001] The invention relates to the technical field of new energy, in particular to a heat pipe metal bipolar plate air-cooled (single) battery stack, a vehicle and electronic equipment. Background technique [0002] Fuel cell is a power generation device that directly converts the chemical energy of fuel and electrolyte into electrical energy. It is also the fourth type of power generation device after thermal power, hydropower, and nuclear power. It is a high-tech development field that developed countries attach great importance to today. [0003] Fuel cell is a promising new power source. It generally uses hydrogen, methanol, borohydride, gas or natural gas as fuel, as the negative electrode, and uses oxygen in the air as the positive electrode. The main difference from ordinary batteries is that the general battery The active material is pre-placed inside the battery, so the battery capacity depends on the amount of active material stored; while the acti...
