Research on BP algorithm-based SOFC system temperature model

Based on BP algorithm, a thermal management model of SOFC system used for marine underwater equipments was established, and linear prediction was performed on the model. Through repeated training on the convergence chamber, heat exchanger and stack respectively, appropriate parameters were selected to conduct testing on the trained model. The deviation between the test result and actual date can meet the requirements. Training and testing on the BP algorithm-based model of SOFC system were performed using the same data. The deviation between the test result and the actual data was about ±1□. This model can provide important theoretical and methodological support for the development of the prototype SOFC power system.
