Problems solved by technology

[0004] Due to the large volume of the battery stack, the volume of the outer heating furnace is usually larger, which is not convenient for mobile installation and later maintenance of the battery stack. In addition, the selection of a simple heating device cannot ensure that the battery stack is evenly heated

Abstract

The invention discloses a molten carbonate fuel cell stack heating device and a working method thereof, and belongs to the technical field of high-temperature fuel cells. The molten carbonate fuel cell stack heating device comprises a control system, a plurality of temperature measuring devices and a plurality of heating furnace modules, wherein the heating furnace module comprises a furnace body,a plurality of grooves are formed in the heating surface of the furnace body, furnace wires are arranged in the grooves, and are connected in parallel, the heating furnace modules are connected in parallel through electric wires, the adjacent heating furnace modules are detachably connected through locking devices, the temperature measuring devices and the electric wires are respectively connected with the control system, the heating furnace modules are arranged on the side face of a battery stack, and the temperature measuring devices are arranged in different areas of the battery stack. According to the invention, the temperature measuring devices feed back the temperatures of different regions of the battery stack in real time, perform regional control on the battery stack, and are uniform in heating and high in efficiency, and when a single module is damaged due to faults, the overall heating effect of the device is not affected, so that reliability and stability are high; and themodules are convenient to mount and dismount, so that mounting and daily maintenance work of the internal battery stack are facilitated.

Description

technical field [0001] The invention belongs to the technical field of high-temperature fuel cells, and in particular relates to a molten carbonate fuel cell stack heating device and a working method thereof. Background technique [0002] Fuel cell power generation technology is a clean and efficient energy converter that can directly convert chemical energy into electrical energy, avoiding the heat loss caused by the Carnot heat engine cycle, and has the advantages of low noise, no pollution, and high efficiency. [0003] As a high-temperature fuel cell, the molten carbonate fuel cell works at a temperature of 650°C and needs continuous heat from the outside to maintain the working temperature. At the same time, the molten carbonate fuel cell adopts the in-situ roasting process, which requires In the process of working conditions, heat is continuously obtained to complete the heating and roasting of the battery stack. [0004] Due to the large volume of the battery stack, ...
