Infinity Fuel Cell and Hydrogen, Inc. has achieved a significant milestone by delivering a 7 kW Proton Exchange Membrane (PEM) Hydrogen Fuel Cell for future spaceflight missions. This fuel cell stack, designed for a commercial space customer, has successfully completed acceptance testing and is among the largest fuel cell stacks produced by Infinity. Engineers tested the stack's performance within the range of 1 to 7 kW to meet operational requirements. The company's patented air-independent, space-rated fuel cell systems offer support for extended mission operations, providing tactical and logistical advantages for upcoming flight and lunar surface missions. William Smith, the CEO of Infinity, emphasized the importance of these fuel cell systems in advancing electrical power solutions for space applications. He noted that once fully qualified, these systems could fill a significant capability gap left by the retirement of the Space Shuttle fuel cell, offering NASA and commercial spaceflight customers an essential option for long-duration flights and lunar missions. Founded in 2002, Infinity Fuel Cell and Hydrogen, Inc. is a renowned market leader in designing air-independent electrochemical systems, including fuel cell systems tailored for space and underwater use. In addition to its space applications, the company is also actively developing electrolysis technologies capable of generating hydrogen and oxygen at high pressures, further expanding its capabilities in sustainable energy solutions.
