Herein, we report the potential of SOFCs as neuromorphic computing devices and verify the synaptic properties, including paired-pulse facilitation (PPF) and potentiation and depression characteristics, under specific operating conditions, which enable the implementation of a brain-like computing system. We simulate image classification tasks using an artificial neural network (ANN) and confirm that the classification accuracy is 85.4%, indicating that the SOFC system is capable of performing cognitive computing in addition to having power generation functionality. This work examines the concept of in-cell computing using bifunctional SOFCs that handle computation/memory functions in electric power generation devices, and our findings suggest opportunities for power management in various sectors, including smart grid systems, electric vehicles, and smart mobility.
