Hydrogen must be stored at high pressures to achieve the energy density required for use in fuel cell vehicles and infrastructure. This presentation will demonstrate the performance attributes required of fittings used in these systems.

As a small-molecule gas, hydrogen can migrate through tiny crevices and diffuse into the materials designed to contain them. Also, high storage and dispensing pressures, as well as rapid thermal and pressure changes, are challenges for the processing of hydrogen as a fuel source. Specification of high-performing fluid system fittings designed for these challenging applications will help ensure the long-term, leak-tight operation of the system.
