Quantum has developed and launched a line of 5,000 and 10,000-psi hydrogen-refueling systems to support the introduction of fuel cell vehicles. Quantum's portable refueling units are designed to be user friendly based on simple and fully automated controls. They feature an interactive touch screen, one-button operation, automatic shut-off, and incorporate multiple redundant safety mechanisms and fueling controls compatible with California Fuel Cell Partnership hydrogen refueling protocols. The units are also designed with a defueling capability, which is an important feature that facilitates vehicle service operations. They operate on standard industrial power and do not have special utility requirements.

Quantum's refuelers are certified for use by Germany's regulatory agency, TUV (Technischer Uberwachungs Verein). Certification agencies and industry specifications require the units to safely manage pressure, temperature, and potential gas leakage issues with redundant safety features and thorough test and validation of components and systems.

"Our transportable refueling systems are designed to support our customers as they develop and demonstrate their fuel cell vehicles in the field," stated Alan P. Niedzwiecki, President and CEO. "These systems are also helping to establish the early foundation of a hydrogen refueling infrastructure that is beginning to take shape as we move toward a hydrogen economy.

"The higher pressure storage systems developed by Quantum, which this new refueling system supports, translate directly into a greater vehicle driving range for hydrogen fueled vehicles, a critical factor for the commercialization of fuel cell vehicles," added Niedzwiecki.
