The high-efficiency energy conversion process in organisms is usually carried out by organelles, proteins and membrane systems. Inspired by the cellular aerobic respiration process, we present an artificial electricity generation device, aimed at sustainable and efficient energy conversion using biological components, to demonstrate the feasibility of bio-inspired energy generation for renewable energy solutions. This approach bridges biological mechanisms and technology, offering a pathway to sustainable, biocompatible energy sources. The device features a mitochondria anode and oxygen-carrying red blood cells (RBCs) cathode, alongside a sandwich-structured sulfonated poly(ether ether ketone) and polyimide composite nanochannel for efficient proton transportation, mimicking cellular respiration. Achieving significant performance with 40 wt% RBCs, it produced a current density of 6.42 mA cm and a maximum power density of 1.21 mW cm, maintaining over 50% reactivity after 8 days. This research underscores the potential of bio-inspired systems for advancing sustainable energy technologies.
生物体中的高效能量转换过程通常是由细胞器、蛋白质和膜系统来完成的。受细胞需氧呼吸过程的启发，我们提出了一种人工发电装置，旨在利用生物组件进行可持续和高效的能量转换，以展示生物启发型能源产生对于可再生能源解决方案的可行性。这种方法将生物学机制和技术联系起来，为可持续、生物兼容的能源提供了一种途径。该装置采用线粒体作为阳极，携氧的红细胞（RBC）作为阴极，同时采用磺化聚醚醚酮和聚酰亚胺复合纳米通道作为三明治结构，以实现高效质子传输，模拟细胞呼吸。在 40wt% RBC 的情况下，该装置实现了显著的性能，产生了 6.42 mA cm 的电流密度和 1.21 mW cm 的最大功率密度，在 8 天后仍保持超过 50%的反应活性。这项研究强调了生物启发系统在推进可持续能源技术方面的潜力。
