## 1 Introduction  
In a university setting, a solar-hydrogen system serves multiple roles, including community involvement, education, research, and sustainability [1, 2, 3]. It exemplifies the university's commitment to environmental responsibility by providing a clean energy source and reducing reliance on fossil fuels through solar-powered electrolysis [4, 5, 6, 7]. This aligns with efforts to promote sustainable behaviors and combat climate change [8, 9]. The system also enhances instructional initiatives by offering hands-on learning opportunities in environmental science, energy management, and renewable technologies, acting as a living laboratory [10, 11]. Engagement with the system equips students with practical experience and prepares them for careers in related fields [11, 12]. Additionally, it enriches-academic programs by offering interdisciplinary learning in subjects such as chemistry, engineering, environmental studies, and policy development [13; 14]. A solar-hydrogen system within the institution serves as a hub for research and innovation. Academic staff and researchers can conduct studies on system optimization, performance monitoring, and technological advancements in hydrogen generation, storage, and utilization [15; 16; 17]. This research contributes to future developments in renewable energy technology and fosters partnerships with businesses and academic institutions to facilitate technology transfer and commercialization [18; 19; 20]. Additionally, the system supports outreach and community involvement initiatives by serving as a focal point for public awareness campaigns and educational events [21; 22; 23]. Partnerships with external entities further promote sustainability projects and the adoption of renewable energy technologies beyond campus boundaries [24; 25; 26]. By integrating sustainable energy solutions into campus operations, universities set a positive example, educate future environmental leaders, and drive societal change [27; 28; 29]. Temperature sensitivity is a problem in proton exchange membrane (PEM) fuel cell research, especially for high-power applications like automobiles. A study looks at this sensitivity and suggests an active temperature control method to improve an 85 kW fuel cell stack's output performance. The research extends prior investigations by quantitatively analyzing temperature effects using a semi-empirical equivalent circuit model and electrochemical impedance spectroscopy. The paper also presents an active temperature control method with temperature tracking and a decoupling management strategy designed for high-power PEM fuel cell stacks. By combining a Takagi-Sugeno fuzzy theory coupling algorithm, a simplified temperature tracking control linear model, and Model Predictive Control (MPC), this method effectively regulates operational temperature in response to variations in load current, hence optimizing stack performance [30]. The study highlights how crucial it is to deal with PEM fuel cells' temperature sensitivity problems in order to successfully integrate them into high-power applications. Furthermore, in order to prevent flooding and preserve gas diffusion efficiency, advancements in Gas Diffusion Layer (GDL) water management are crucial for enabling the large-scale commercialization of PEMFCs [31]. Electrochemical energy conversion and storage (EECS) devices show great promise for bridging gaps between energy availability and demand in the larger context of renewable energy integration. These devices offer high efficiency, fast reaction times, scalability, and location independence. These revelations highlight how important it is to develop fuel cell technology as well as energy storage technologies in order to facilitate the broad use of renewable energy sources [32]. The potential of a solar-hydrogen system to meet the institution's energy needs and act as a role model for sustainable energy solutions makes it crucial to deploy in a university setting [33; 34; 35].
