Solid oxide Cell Stack Voltage Emulator

Abstract

Amidst the growing urgency of the climate crisis, alternative energy technologies have garnered increasing attention for their potential in power generation applications. Notably, the solid oxide cell (SOC) system has emerged as a highly efficient player in the power-to-x process. However, the intrinsic cost and susceptibility to testing disruptions have underscored the need for innovative solutions. In this context, the development of a solid oxide cell emulator surfaces as a crucial enabler for research and experimentation. Creating a SOC emulator entails a multi-faceted endeavour, necessitating the implementation of electrical, thermal, and fluidic domains. This study is devoted to the realization of a stack voltage emulator. Utilizing KiCad, a comprehensive open-source electronic design automation suite, facilitated the implementation of an intricate circuit that encompasses both the digital and analogue realms of voltage emulation. The primary objective of this study was to design and simulate the behaviour of the stack voltage emulator through a meticulous analysis of digital and analogue components. The aim was to achieve accurate and dependable replication of stack voltage characteristics. The simulation results offer profound insights into the system’s performance, stability, and response attributes. Methodologically, this study encompasses the design specification, circuit design, parametric search of components, a schematic and PCB design in KiCad. Our findings resonate across key parameters including voltage gain, linearity, and transient response time analysis. Additionally, the study underscores the implementation of protective mechanisms encompassing current limitations and resilience against short circuits. In essence, this research illuminates a path toward harnessing the potential of solid oxide cell technology through advanced emulation methodologies. The outcomes of this thesis hold the promise of influencing not only the design of SOC emulation systems but also contributing to the broader landscape of sustainable energy solutions.
