This hands-on engineering course guides students through the design, construction, and testing of a hydrogen drone refueling station that generates hydrogen via water electrolysis. Students will explore renewable energy integration, fuel cell technology, and gas storage and safety systems. The course emphasizes practical problem-solving, system integration, and sustainability in energy infrastructure. Teams will develop working prototypes and evaluate their performance through real-world testing with drone refueling scenarios. By the end, students will gain experience in clean energy systems, prototyping, and collaborative engineering design.
