生物燃料电池在过去的世纪一直备受关注，因为它们作为从人体和环境中可持续收集能量的独特平台的潜力和前景。由于生物燃料电池通常在小型平台中开发，用作具有有限燃料的原电池或作为重复加油的可充电电池，因此它们可互换地称为生物电池。然而，尽管不断进步和创造性的概念验证，该技术在过去的100年里一直处于起步阶段，这引起了人们对其商业可行性的越来越多的怀疑。低性能、不稳定性、操作困难以及不可靠和不稳定的发电质疑生物燃料电池的可持续发展。然而，生物电催化的进步彻底改变了生物燃料电池的发电能力，为特定应用提供了有吸引力的实用技术。这篇观点文章将确定导致我们错误发展方向的关于生物燃料电池的误解，并重新审视其可能很快实现的潜在应用。然后，它将讨论所选应用程序商业化需要立即解决的关键挑战。最后，将提供潜在的解决方案。本文旨在启发社区，以便尽快开发出富有成效的商业产品。
Biofuel cells have been in the spotlight for the past century because of their potential and promise as a unique platform for sustainable energy harvesting from the human body and the environment. Because biofuel cells are typically developed in a small platform serving as a primary battery with limited fuel or as a rechargeable battery with repeated refueling, they have been interchangeably named biobatteries. Despite continuous advancements and creative proof-of-concept, however, the technique has been mired in its infancy for the past 100 years, which has provoked increasing doubts about its commercial viability. Low performance, instability, difficulties in operation, and unreliable and inconsistent power generation question the sustainable development of biofuel cells. However, the advancement in bioelectrocatalysis revolutionizes the electricity-producing capability of biofuel cells, promising an attractive, practical technique for specific applications. This perspective article will identify the misconceptions about biofuel cells that have led us in the wrong development direction and revisit their potential applications that can be realizable soon. Then, it will discuss the critical challenges that need to be immediately addressed for the commercialization of the selected applications. Finally, potential solutions will be provided. The article is intended to inspire the community so that fruitful commercial products can be developed soon.
