A fuel cell power generation system adaptive load control system and method

Abstract

The invention discloses an adaptive load control system and method for a fuel cell power generation system. The fuel cell power generation system adaptive load control system includes a fuel cell module, a fuel supply module, an energy storage module and a control module. The invention effectively automatically matches the discharge power of the fuel cell with the load, and performs self-adaptive step-level adjustment along with the change of the load, and simultaneously performs the increase and decrease of the fuel supply and the timely electric energy supplement of the energy storage module. The invention can effectively avoid the impact of the load change on the fuel cell module, avoid the incomplete reaction caused by the hysteresis of the response of the fuel supply module, and even further cause irreversible damage to the fuel cell module, and reduce the charge and discharge of the energy storage module depth, thereby prolonging the life of the fuel cell module and energy storage module, and improving the reliability of the fuel cell power generation system under variable load conditions.

Description

technical field [0001] The invention relates to the technical field of new energy power generation, in particular to an adaptive load control system and method for a fuel cell power generation system. Background technique [0002] As the current field of new energy power generation, the fuel cell power generation system is a fully silent and uninterrupted power generation system. Its core power generation process belongs to a chemical reaction, and the rate of chemical reaction is always affected by some factors, such as: reactant concentration, activation energy , reaction temperature, catalyst, etc. At the same time, the commercial manufacturing process of fuel cell power generation systems is also limited by factors such as volume, quality, efficiency, cost, life, and application environment, making it impossible for any type of fuel cell itself to carry out chemical reactions quickly and directly. Sudden changes, so as to achieve sudden changes in output power; manufact...
