abstract = {High cost and short life-span hinder the large-scale
commercial application of solid oxide fuel cell technology.
System performance inevitably degrades and gradually evolves
into faults in the long run, leading to the change of system
input-output characteristics. The control system designed
based on initial conditions faces with problems such as
parameter mismatch, inaccurate control and even wrong
control laws. This paper proposes an adaptive control
strategy to enable the system controller to cope with
degradation and fault phenomena in real systems. The system
characteristics under different degradation and fault
conditions are investigated. A novel health evaluation
system is developed, where an early fault identification and
pretreatment approach based on optimal operation point
optimization model and fuzzy neural network are adopted for
control optimization. Simulation results show that the
enhanced system controller can improve system efficiency by
about $2\%$ and prolong life-span significantly with the
reality of degradation and fault mechanisms.},
