The invention discloses an extensible fuel cell emergency power generation system, which comprises a plurality of fuel cell power generation modules, a hydrogen supply system, an inverter, a system controller and an electrical interface, wherein an input end of the parallel fuel cell power generation modules is connected with the hydrogen supply system, and an output end of the parallel fuel cell power generation modules is output to a DC / AC (Direct Current / Alternating Current) inverter and then to the electrical interface through a power distribution box; and a system controller is connected with each power generation module, the hydrogen supply system and the DC / AC inverter in a wireless communication mode. Each set of fuel cell power generation module is an independent power generation unit, the normal work of other power generation module units is not affected when a set of fuel cell power generation module fails in the emergency power generation system; when the external demand power is small, the fuel cell does not operate at the optimal working state, so that the service life of the fuel cell is not affected; and the system has a simpler structure and is lower in efficiency.
Description
technical field [0001] The invention relates to an emergency power generation system, more specifically, an expandable fuel cell emergency power generation system. Background technique [0002] The patent with application number 201010208177.2 has the following defects: [0003] 1. The invention uses a 45KW fuel cell module. If there is a single-chip fuel cell performance degradation or failure, it will directly affect the output of the entire system; [0004] 2. When the external power demand is small, the fuel cell is not running in the best working condition, which will affect its service life; [0005] 3. The system architecture is relatively complex and the system efficiency is low. Contents of the invention [0006] The purpose of the present invention is to propose a scalable fuel cell emergency power generation system, which optimizes the system architecture and can solve the above-mentioned problems existing in the prior art. [0007] To achieve the above objec...
