Quality assurance methods for hydrogen energy fuel cells using the “Delta4 Phantom+” diode matrix

Abstract

Hydrogen energy systems require precise verification methods to ensure the efficiency and stability of fuel cells, similar to the high-precision techniques used in tomotherapy. A key stage in ensuring accuracy in radiation therapy is the verification of dosimetric plans, confirming that the delivered dose matches the planned values. Various physical and technical methods assess dose distribution accuracy. The principles of precision verification in tomotherapy share striking similarities with diagnostic and quality assurance techniques in hydrogen energy. Fuel cells require meticulous monitoring of ion transport, energy distribution, and material stability to optimize performance. The methodologies developed for tomotherapy, particularly those utilizing the Delta4 solid-state phantom, can be adapted for assessing spatial energy variations and charge transport efficiency in hydrogen fuel cells. This study explores the capabilities of the Delta4 solid-state phantom, equipped with a two-dimensional diode detector matrix, for verifying tomotherapy plans delivered with the “Tomotherapy HD” linear accelerator. Dosimetric plan quality was assessed using gamma analysis based on international 3%/3 mm criteria, the standard in intensity-modulated radiation therapy. The operational advantages and limitations of the Delta4 phantom were analyzed, including the impact of geometric and dosimetric parameters on measurement accuracy. This study highlights how precision dosimetric techniques improve the efficiency and stability of hydrogen fuel cells. Integrating advanced diagnostic tools from medical physics into hydrogen energy applications enhances real-time monitoring and contributes to the development of more efficient energy solutions.
