Силиконовый шланг для водородных топливных элементов– High Purity, Низкая проницаемость & Долговечный дизайн

Введение

Для систем водородных топливных элементов требуются силиконовые шланги, работающие под high purity air, elevated temperatures, and pressure pulsation, while maintaining extremely low contamination and long-term reliability. HOTOP develops hydrogen fuel cell silicone hoses using a systematic engineering approach, ensuring compliance with automotive and industrial standards.

Ключевые технические проблемы

»Hydrogen Permeation
Hydrogen molecules can penetrate most elastomers, causing efficiency loss. HOTOP uses low-permeation silicone compounds to minimize leakage.

»Particle Contamination
Fuel cells are sensitive to particulates. Hoses are manufactured under clean production conditions to prevent contamination.

»Thermal Aging
Continuous high temperatures can cause silicone hardening or cracking. HOTOP materials are optimized for thermal stability and long-term elasticity.

»Pressure Pulsation & Fatigue
Repeated pressure cycles may cause delamination or structural fatigue. Reinforcement and hose geometry are engineered for high-pressure endurance.
