In the period of gas outage for maintenance in high pure hydrogen system,such as gasholder,equipment,pipe,etc,traditional purge method is used during the processing of high purity hydrogen system.

This paper introduces the necessity and feasibility of improving Russian hydrogen leakage on-line monitor in the generator hydrogen cooling system of unit 1,and the operation,the calibration and the maintenance of the devices improved.

The quantity of hydrogen leakage rate of the generator hydrogen system is one of the main technical indexes for the unit operation and the hydrogen leakage has direct impact on the safe and reliable operation of the units.

Hydrogen system is installed on the trolley according the on Fuel Cell Bus.

： This paper deals with the higher cost of construction projects for thermal power plant in China． One of the solutions is presented， which is about auxiliary facilities． Based on calculation and technical－economic comparison in detail for both hydrogen generating station and bottled hydrogen supply system， scheme of bottled hydrogen supply system for hydrogen－cooled turbogenerator is proposed

This paper has realized the software and hardware of the hydrogen supply system in fuel cell buses from the view of project practice, including the designs and realizations for hydrogen supply system and hydrogen safeguard system.
