(Archived) Praxair Introduces New Fuel Cell Grade Hydrogen
DANBURY, Conn., March 13, 2003 — Praxair, Inc. (NYSE:PX) announced today the launch of a new high purity hydrogen (H2) grade for fuel cell applications — the only one in the industry. The introduction of this new product offering is in direct response to fuel cell manufacturers' requests for higher purity hydrogen. A fuel cell is an electrochemical device that combines hydrogen (fuel) and oxygen (from the air) to produce electricity, pure water and heat.
"The presence of contaminants like ammonia (NH3), carbon monoxide (CO) and sulfur compounds can harm the catalyst-coated membranes inside the fuel cell, reducing its efficiency," said Janet Coffman, vice president of marketing and business development, Praxair Distribution, Inc. "Praxair's new fuel cell grade hydrogen, available in high-pressure cylinders, contains extremely low levels of these impurities, helping maintain the performance and reliability of these devices."
Due to its strict specification, the new hydrogen fuel cell grade cylinder is filled only at specific Praxair specialty gases production facilities. From product source and cylinder preparation to cylinder filling and analytical testing, all steps of the production process are key to achieving and maintaining reliable and consistent purity levels.
For the past decades, Praxair has been working with materials providers, device suppliers, end-use customers and government on the development of new, clean fuel technologies, including fuel cells for electricity and mobile power generation. In 2000, Praxair was chosen by the U.S. Department of Energy (DOE) to lead one of eight teams that will pioneer a new generation of ultra-clean, transportation fuels and associated emission controls to meet stringent tailpipe emission standards later this decade.
