This paper is an analysis of driving characteristics of a metal-hydrogen (MH) actuator for driving a rehabilitative system using environmentally friendly hydrogen. The temperature–pressure characteristics of the MH actuator according to the temperature control of the Peltier element were analyzed to apply to the driving of the rehabilitative system to assist the daily activities of the patient. In this experiment, Peltier element is used to control the temperature of MH module which contains hydrogen storage alloy with on/off control scheme and fan on/off. To improve the thermal conductivity of the hydrogen-absorbing alloy, an assembly of MH module based on copper has been used. The control currents of the thermoelectric elements were 1 A and 2 A, and the temperature control range was between 35° and 70°. As the result of experiments, it is proper to act fan only while cooling duration and there exist a proper cooling current to drop temperature rapidly. It takes about 100 s to increase to 70 °C and drop to 35 °C of MH module temperature and about 90 s to increase to 70 °C and drop to 40 °C in ambient temperature 30 °C while fan is on only in cooling duration. The desirable characteristics of MH actuator, which makes it suitable for the uses in medical and rehabilitation applications, have been also studied.

本文是对使用环保氢气驱动修复系统的金属氢（MH）执行器的驱动特性进行的分析。根据Peltier元件的温度控制对MH执行器的温度-压力特性进行了分析，以应用于康复系统的驱动，以协助患者的日常活动。在该实验中，珀尔帖元件用于通过开/关控制方案和风扇开/关控制包含储氢合金的MH模块的温度。为了提高吸氢合金的导热性，已经使用了基于铜的MH模块的组件。热电元件的控制电流为1A和2A，并且温度控制范围在35°至70°之间。经过实验，仅在冷却期间才使用风扇是适当的，并且存在适当的冷却电流以迅速降低温度。当风扇仅在冷却状态下打开时，在MH模块温度下升至70°C并降至35°C大约需要100 s，在环境温度30°C时要升至70°C并降至40°C大约需要90 s。持续时间。还研究了MH执行器的理想特性，使其适用于医疗和康复应用。
