Title:

HYDROGEN LEAKAGE PREVENTION STRUCTURE

Document Type and Number:

Japanese Patent JP2017172669

Kind Code:

A

Abstract:

PROBLEM TO BE SOLVED: To provide a hydrogen leakage prevention structure capable of suppressing deterioration of hydrogen detection performance due to adhesion of dust or the like, and suppressing diffusion of leaked hydrogen gas.SOLUTION: A hydrogen leakage prevention structure 10 includes: an airtight tubular structure part 20 configured to connect a hydrogen tank 2 and a fuel battery stack 3 in a state where at least a part therebetween is made into an airtight state; a hydrogen supply system 30 arranged in the airtight tubular structure part 20, and configured to supply hydrogen from the hydrogen tank 2 to the fuel battery stack 3; an optical fiber hydrogen sensor 40 arranged in the airtight tubular structure 20, and configured to detect hydrogen; and a hydrogen occlusion alloy 50 arranged in the airtight tubular structure 20, and configured to occlude hydrogen.SELECTED DRAWING: Figure 2
