Water electrolysis using a proton exchange membrane (PEM) holds substantial promise to produce green hydrogen with zero carbon discharge. Although various techniques are available to produce hydrogen gas, the water electrolysis process tends to be more cost-effective with greater advantages for energy storage devices. However, one of the challenges associated with PEM water electrolysis is the accumulation of gas bubbles, which can impair cell performance and result in lower hydrogen output. Achieving an in-depth knowledge of bubble dynamics during electrolysis is essential for optimal cell performance. This review paper discusses bubble behaviors, measuring techniques, and other aspects of bubble dynamics in PEM water electrolysis. It also examines bubble behavior under different operating conditions, as well as the system geometry. The current review paper will further improve the understanding of bubble dynamics in PEM water electrolysis, facilitating more competent, inexpensive, and feasible green hydrogen production.
使用质子交换膜（PEM）进行水电解在生产零碳排放的绿色氢气方面具有巨大潜力。尽管有多种制氢技术，但水电解过程往往更具成本效益，对储能设备具有更大优势。然而，与PEM水电解相关的挑战之一是气泡的积累，这会损害电池性能并导致氢气产量降低。深入了解电解过程中的气泡动力学对于实现最佳电池性能至关重要。这篇综述论文讨论了PEM水电解中气泡的行为、测量技术以及气泡动力学的其他方面。它还研究了不同操作条件下以及系统几何形状下的气泡行为。当前的综述论文将进一步增进对PEM水电解中气泡动力学的理解，促进更高效、廉价且可行的绿色氢气生产。
