The aim of this research is to prod uce the enzyme bilirubin oxidase through stress-induced expression in Baci llus subtilis and to evaluate its application as a cathodic biocatalyst fo r the oxygen reduction reaction in a hybrid hydrogen fuel cell. The study focuses on identifying ideal conditions to enhance enzymatic activity and operational stability under electrochemical conditions relevant to fuel ce ll operation. The sources of cellular stress in this study will be nitroge n starvation and the presence of copper ions in growth media\, both of whi ch have been linked to increased Bilirubin Oxidase activity. In addition\, graphene oxide will be employed as a conductive interfacial material to i mprove enzyme immobilization\, orientation\, and utilization on carbon fib er electrodes. Owing to its high specific surface area\, excellent biocomp atibility\, and abundance of functionalizable oxygen-containing groups\, g raphene oxide facilitates strong enzyme–electrode interactions and promo tes favorable catalytic orientation for efficient electron transfer. The s ynergistic integration of bilirubin oxidase\, graphene oxide\, and carbon fiber will improve cathodic performance while maintaining long-term stabil ity of the system. Ultimately\, this work seeks to advance the development of efficient and durable bio-based cathodes for fuel cell applications.
