Catalytic combustion and thermoelectric conversion integrated power generation device

Abstract

The invention discloses a catalytic combustion-thermoelectric conversion integrated power generation device comprising a plurality of power generating units. Each power generating unit is composed ofan upper catalytic combustion unit, a lower catalytic combustion unit and a thermoelectric conversion unit. The combustion units are formed by cold-end channels, flow channels, and hot-end channels. The thermoelectric conversion units include hot-end conductive films, cold-end conductive films, P type semiconductor thin-film thermoelectric elements and N type semiconductor thin-film thermoelectricelements, wherein the P type semiconductor thin-film thermoelectric elements and the N type semiconductor thin-film thermoelectric elements are arranged between the hot-end conductive films and the cold-end conductive films; the hot-end conductive films and the cold-end conductive films are arranged at the cold-end channels and the hot-end channels; and catalysts are deposited on the hot-end conductive films uniformly. The semiconductor thin-film thermoelectric elements inside all power generating units are separated by insulating substrates; and the power generating units are separated by insulating layers. According to the catalytic combustion-thermoelectric conversion integrated power generation device, the heat generated by catalytic combustion can be transferred to the thermoelectricdevice directly, so that the space is saved and energy losses are reduced.

Description

technical field [0001] The invention relates to the technical field of thin-film thermoelectric power generation, in particular to a catalytic combustion and thermoelectric conversion integrated power generation device. Background technique [0002] Power generation is the process of converting non-electric energy into electrical energy. At present, common forms of power generation include hydropower, thermal power, wind power, solar power, ocean power, nuclear power, etc., among which thermal power is the main form of power generation. . Thermal power generation is a form of power generation that utilizes the heat energy generated during combustion of combustibles and converts it into electrical energy through a power generation unit. [0003] Combustibles that store energy in the form of chemical bonds, such as methanol and formaldehyde, are usually converted to heat rather than directly to electricity. Typically, this energy conversion occurs at high temperatures and oft...
