Title:
HOSE FOR FUEL CELL
Document Type and Number:
Japanese Patent JP2011103302
Kind Code:
A
Abstract:
To provide a hose for a fuel cell, which can lessen increase of conductivity of pure water and is excellent in insulation.
The hose for a fuel cell is formed with a thermoplastic elastomer composition. A conductivity increase value (μs/cm) of pure water in the optimal thermoplastic elastomer composition after being immersed in the pure water for 7 days is preferably 5 or less. Further, the thermoplastic elastomer composition preferably has a hardness of A90 or less (type A durometer hardness), and is flexible. Olefin thermoplastic elastomer polymerized at a multi-step in a reactor is used as this thermoplastic elastomer composition.
