1. Introduction

HYH-300﹙500﹚type high purity hydrogen generator is a new type product developed on the foundation of the technology of astronautic fuel cells. The working principle of hydrogen generator is, hydrogen is produced by the electrolysis of water, and the produced oxygen is released to the atmosphere. It is made up of these systems such as the electrolyzing &separating pool, switch power, pressure control, desiccation& purification and flow display.

The core part of the instruments is electrolyzing &separating pool, in which the positive pole is of tube type structure, the negative pole is of sheet metal shape, and both the poles are made of stainless steel. The electrolyzing &separating pools can store electrolyte, produce hydrogen as well as release hydrogen at the same time, and it is the best replacement to sheet shaped electrolyzing pools. The instruments have advantage such as the large electrolyzing area, low pool temperature, large production of hydrogen with high purity. The instruments are specially installed with the devices that can prevent liquid from returning, so the instruments can be effectively guaranteed that the phenomenon of liquid returning doesn’t occur during working.
