Portable hydrogen micro-combustion thermoelectric radiation enhanced thermionic power supply device and method

Abstract

The invention discloses a portable hydrogen micro-combustion thermoelectric radiation enhanced thermionic power supply method and device. And hydrogen in the high-pressure hydrogen storage tank and air pumped by the micro air suction pump are premixed in the pipeline and are introduced into the micro combustion chamber for combustion. The hydrogen flame heats the cathode through the wall face of the micro-combustion chamber, free electrons in the cathode are thermalized and enter the N-type semiconductor in a hot electron emission mode, and after being secondarily thermalized in the N-type semiconductor, the free electrons overcome the N-P junction interface potential barrier in a thermoelectric radiation mode to enter the P-type semiconductor and return to the cathode again through a wire and a load, and power generation is achieved. Hydrogen micro-combustion is adopted for energy supply, low carbon and environmental protection are achieved, and circulating power supply is rapid. Thermoelectric conversion is carried out in a thermoelectric radiation enhanced thermoelectron power generation mode, the heat energy utilization rate is high, the conversion efficiency from hydrogen chemical energy to electric energy is high, and the whole device has the characteristics of high specific energy density and high specific power.

Description

Technical field [0001] The present invention relates to the field of hydrogen micro-combustion power supply, and more particularly to devices and methods of hydrogen micro-combustion thermoelectric radiation reinforced thermoconics. Background technique [0002] Nowadays, more people are favored outdoor sports, I like to experience nature outdoors, but outdoors are inconvenient, often do doing mobile power. The main use of the market is mainly a lithium battery, but it charges and discharge rates, smaller than energy density, and disposal of waste lithium batteries will also cause greater pollution. Hydrogen can be a fuel that is the most cleaner and energy density is an ideal chemical energy storage medium. The source of zero carbon is mainly converted to hydrogen energy to hydrogen energy by electrolysis, etc., which is used to supply electricity. A hydrogen fuel cell is an elevated power supply for direct power generation of hydrogen, but power generation performance will dete...
