摘　　要：以45kW质子交换膜燃料电池及其实验平台为例,进行基于卡尔曼滤波的燃料电池欧姆内阻的估算,建立基于内阻估算结果的热功率计算数学模型。对于热功率值的验证,采用校正后的燃料电池数学模型,以模型中的热功率计算值为比较对象。研究结果表明:基于燃料电池估算的欧姆内阻建立的热功率计算数学模型具有可行性,为燃料电池热管理提供了新的研究方向,对制定控制策略提供了新思路。In this paper,a 45 kW PEMFC and the experimental bench were taken as an example.Firstly,the fuel cell ohmic resistance was estimated based on the Kalman filter algorithm.Secondly,the fuel cell thermal power calculated model was built based upon the ohmic resistance.The model was validated by taking the revision thermal model in the references as a comparison.The research results show that there is certain feasibility about building fuel cell thermal power calculated model based the ohmic resistance.It provides a new research area and control strategy for exploring PEMFC thermal management.
