Industrial Internet of Things has significantly boosted predictive maintenance for complex industrial systems, where the accurate prediction of remaining useful life with high-level confidence is challenging. By aggregating multiple informative sources of system degradation, information fusion can be applied to improve the prediction accuracy and reduce the uncertainty. It can be performed on the data-level, featurelevel, and decision-level. To fully exploit the available degradation information, this paper proposes a hybrid fusion method on both the data level and decision level to predict the remaining useful life. On the data level, Genetic Programming is adopted to integrate physical sensor sources into a composite health indicator, resulting in an explicit nonlinear data-level fusion model. Subsequently, the predictions of the remaining useful life based on each physical sensor and the developed composite health indicator are synthesized in the framework of belief functions theory, as the decision-level fusion method. Moreover, the decision-level method is flexible for incorporating other statistical data-driven methods with explicit estimations of the remaining useful life. The proposed method is verified via a case study on NASA's C-MAPSS data set. Compared to the singlelevel fusion methods, the results confirm the superiority of the proposed method for higher accuracy and certainty of predicting the remaining useful life.

“…Therefore, the accuracy of the fusion approach should be higher than both model and data driven approaches when used individually [26], although for a real-time analysis it may not be suitable due to 215 the significant computational resources required. The fusion approach has been reported to be used in many applications before [26,64,65,66,67,68,69].…”

“…As prognostics can provide state-of-health (SOH) and RUL information of the fuel cell, the operation of the fuel cell can be optimised using an appropriate control strategy. Maintenance tasks can be scheduled, thus 65 reducing down time. Although prognostics was used in safety critical systems in early days, it is nowadays an integral part in many engineering systems, products and applications [26].…”

Fuel cell technology can be traced back to 1839 when British scientist Sir William Grove discovered that it was possible to generate electricity by the reaction between hydrogen and oxygen gases. However, fuel cell still cannot compete with internal combustion engines although they have many advantages including zero carbon emissions. Fossil fuels are cheaper and present very high volumetric energy densities compared with the hydrogen gas. Furthermore, hydrogen storage as a liquid is still a huge challenge. Another important disadvantage is the lifespan of the fuel cell because of their durability, reliability and maintainability.Prognostics is an emerging technology in sustainability of engineering systems through failure prevention, reliability assessment and remaining useful lifetime estimation. Prognostics and health monitoring can play a critical role in enhancing the durability, reliability and maintainability of the fuel cell system. This paper presents a review on the current state-of-the-art in prognostics and health monitoring of Proton Exchange Membrane Fuel Cell (PEMFC), aiming at identifying research and development opportunities in these fields. This paper also highlights the importance of incorporating prognostics and failure modes, mechanisms and effects analysis (FMMEA) in PEMFC to give them sustainable * Corresponding author Email address: (tsutharssan@iee.org) (Thamo Sutharssan)Preprint submitted to Renewable & Sustainable Energy Reviews November 14, 2016 competitive advantage when compared with other non-clean energy solutions.
