This paper provides an overview of a Proton Exchange Membrane (PEM) hydrogen fueling apparatus. This apparatus generates hydrogen at elevated pressure and stores the gas in high pressure tubes. PEM hydrogen generation offers a practical, low risk, near-term solution for meeting the needs of early hydrogen vehicles. The systems are modular, easily scalable, proven technology, safe, reliable and currently being produced for a variety of Industrial Gas applications.
In addition to the practicality of PEM electrolysis, pure hydrogen offers many advantages. The only impurity in the gas stream is water vapor, making it the only route to zero-emission vehicles. The system is a low temperature operation, which offers instant start capability. The system requires only water and electricity as process inputs, making every gas station a viable candidate for this process. Lastly, a strong push into near-term markets, and a synergy with PEM fuel cells are continually strengthening the economic viability of electrolysis.
