水裂解制氢清洁环保，有望成为未来重要的能源。本文研究了由水裂解产生的氢气驱动的作动器，建立了双晶型氢作动器的氢致应力模型。通过对带有钯电极（Pd-PVC）的聚氯乙烯电极软致动器的试验，定量评价了水劈裂过程中吸氢引起的应力和弯矩。结果表明：钯电极的厚度影响Pd-PVC致动器的力学性能，钯电极越薄，其弯矩和尖端位移越大；提出了一个简单的力学-电化学耦合方程来描述弯矩、应力和用于水分裂的电荷之间的关系。钯电极软致动器既可作为制氢/储氢机构，也可作为机械致动器，可作为小型系统或微、纳米器件的电源。
Hydrogen production by water splitting is expected to be a significant power source in future because of its cleanness and environment-friendliness. In this study, an actuator driven by hydrogen produced by water splitting is studied and a hydrogen-induced stress model for a bimorph-type hydrogen actuator is developed. From the examination of the soft actuator having electrodes made of polyvinyl chloride with palladium electrode (Pd-PVC), the stress and bending moment induced by hydrogen absorption during water splitting are quantitatively evaluated. The results show that the thickness of the palladium electrode affects the mechanical performance of the Pd-PVC actuator, with the thinner palladium electrode showing a larger bending moment and tip displacement. A simple mechano-electro-chemical coupling equation is proposed to describe the relationship between bending moment, stress, and the electric charge used for water splitting. A palladium electrode soft actuator can work as a hydrogen generator/storage mechanism and as a mechanical actuator, and it can be useful for the power source of small systems or micro- or nano-devices.
