Abstract

The invention discloses a method for processing faults of a solid oxide fuel cell system, which belongs to the field of fuel cells. The method includes: obtaining the drift characteristics of the system under different fault types, different fault degrees, and different power points relative to the non-fault situation ; Obtain the current state parameters of the system in real time, and identify the system fault type and degree according to the drift characteristics; according to the identified fault type and degree, carry out corresponding engineering processing on the system. The method of the present invention conducts real-time identification of system fault types and fault degrees based on the health degree evaluation system, and performs corresponding processing on the identified different fault types and fault degrees, so as to avoid damage to system components that is difficult to repair and fault handling to the system to the greatest extent. The secondary damage caused effectively reduces the impact of the fault outbreak on the system operation, improves the system operation efficiency, realizes the system low-cost, long-life operation, and is suitable for practical engineering applications.

Description

technical field [0001] The invention belongs to the field of fuel cells, and more specifically relates to a method for processing faults in a solid oxide fuel cell system. Background technique [0002] Solid oxide fuel cell (Solid Oxide Fuel Cell, SOFC) can directly convert the chemical energy in hydrocarbon fuel into electrical energy through electrochemical reaction, without combustion and mechanical transmission process, so it has the advantages of quietness, high efficiency and no pollution. Compared with energy storage batteries, SOFC power generation technology has high energy ratio and strong endurance. It is an ideal power supply device for drones and unmanned boats for long-distance long-distance operations. Therefore, it has broad applications in military defense, distributed power supply and other fields. Application prospect. After decades of development, SOFC technology has gradually matured in terms of materials, stack manufacturing, and system integration. Ma...
