“…It helps to clarify the complex relationship between the transport of reactants/end products and cell performance. With the help of CFD, it is effortless to obtain detailed reports on transport mechanisms and analyze fuel cell performance by overcoming the difficulties faced during the experimental approach [9]. Recently, CFD modeling has been chiefly used in conventional O-SOFCs to analyze and optimize their performance, but its usage in PCFCs is minimal [35].…”

“…Recently, Akenteng et al [9] designed a new PCFC model with an inter-parallel flow field (Figure 7a,b) [9]) possessing three unique flow path features to remove water effectively from the cathode side of the PCFC stack. It is also compared with the PCFC stack made up of conventional flow patterns such as serpentine, parallel, and interdigitated flow channel structure.…”

Protonic ceramic fuel cells (PCFCs) are one of the promising and emerging technologies for future energy generation. PCFCs are operated at intermediate temperatures (450–750 °C) and exhibit many advantages over traditional high-temperature oxygen-ion conducting solid oxide fuel cells (O-SOFCs) because they are simplified, have a longer life, and have faster startup times. A clear understanding/analysis of their specific working parameters/processes is required to enhance the performance of PCFCs further. Many physical processes, such as heat transfer, species transport, fluid flow, and electrochemical reactions, are involved in the operation of the PCFCs. These parameters are linked with each other along with internal velocity, temperature, and electric field. In real life, a complex non-linear relationship between these process parameters and their respective output cannot be validated only using an experimental setup. Hence, the computational fluid dynamics (CFD) method is an easier and more effective mathematical-based approach, which can easily change various geometric/process parameters of PCFCs and analyze their influence on its efficiency. This short review details the recent studies related to the application of CFD modeling in the PCFC system done by researchers to improve the electrochemical characteristics of the PCFC system. One of the crucial observations from this review is that the application of CFD modeling in PCFC design optimization is still much less than the traditional O-SOFC.
