Abstract: “Due to the influence of different parameters,the electricity generated by the proton exchange membrane (PEM)fuel cell is not continuous. So, to provide the dynamic response for variable load and to meet the transient as well as peak load demand PEM fuel cell is connected with Li-ion Battery and made a hybrid power supply system. Such type of hybrid system has zero environmental effects and also solve the fossil fuel energy crisis in every country.But in this type of hybrid system, temperature effects is one of the most significant parameters which directly influence the performance of the system. So, in this paper, we are trying to investigate the detail design and effect of temperature parameters on hybrid system.Also, we are trying to monitoring, analyze and control the temperature effects through monitoring and control unit. The real time data communication for remote monitoring and control of hybrid system, a LMS estimation is used. By the use of this method, probability of energy”
