Energies based on biomaterials attract a lot of interest as next-generation energy because biomaterials are environmentally friendly materials and abundant in nature. Fuel cells are also known as the clean and important next-generation source of energy. In the present study, to develop the fuel cell based on biomaterials, a novel biofuel cell, which consists of collagen electrolyte and the hydrogen fuel generated from photochemical system II (PSII) in photosynthesis, has been fabricated, and its property has been investigated. It was found that the PSII solution, in which PSII was extracted from the thylakoid membrane using a surfactant, generates hydrogen by the irradiation of light. The typical hydrogen-generating rate is approximately 7.41 × 10 molecules/s for the light intensity of 0.5 mW/cm for the PSII solution of 5 mL. The biofuel cell using the PSII solution as the fuel exhibited approximately 0.12 mW/cm. This result indicates that the fuel cell using the collagen electrolyte and the hydrogen fuel generated from PSII solution becomes the new type of biofuel cell and will lead to the development of the next-generation energy.
基于生物材料的能源作为下一代能源引起了广泛关注，因为生物材料是环境友好型材料且在自然界中储量丰富。燃料电池也被认为是清洁且重要的下一代能源。在本研究中，为了开发基于生物材料的燃料电池，制备了一种新型生物燃料电池，它由胶原蛋白电解质和光合作用中光化学系统II（PSII）产生的氢燃料组成，并对其性能进行了研究。研究发现，使用表面活性剂从类囊体膜中提取PSII得到的PSII溶液，在光照下会产生氢气。对于5 mL的PSII溶液，当光强为0.5 mW/cm²时，典型的产氢速率约为7.41×10⁻⁹分子/秒。使用PSII溶液作为燃料的生物燃料电池表现出约0.12 mW/cm²的功率。这一结果表明，使用胶原蛋白电解质和PSII溶液产生的氢燃料的燃料电池成为了新型生物燃料电池，并将引领下一代能源的发展。
