The patent, #DE 11 2012 005 583 T5, focuses on “passive and orientation independent means of meeting a key design requirement of water and gas separation within electrochemical cells.”

According to Infinity, the design can benefit both air independent fuel cells and hydrogen-air fuel cells, as well as electrolysis cells, and could simplify the operation of fuel cells and electrolysers for use in a variety of transportation applications, including space, underwater and aircraft.

The technology previously received a US patent and has been a cornerstone of the company’s air independent fuel cell and electrolyser designs.

“The issuing of this patent opens greater international market supply chain opportunities,” said Rick Mullins, Director of Business Development at Infinity Fuel Cell and Hydrogen.

In September last year (2022), the company announced it was actively exploring new opportunities for its air-independent non-flow-through fuel cells in the unmanned underwater vehicle (UUV) market.

Thank you for taking five with H2 View today. For some of our readers who may not be familiar with Infinity, could you tell us a little about the company, its origins and activities?

Infinity was founded in 2002. It’s roots, like so many of the major North American fuel cell companies, sprouted from the Hamilton-Standard division of United Technologies (now the Collins division of Raytheon). This is where a key core group of our senior staff, me included, had our start in this business. For most of our 20 years, we have been a contract R&D firm, specialising in air-independent hydrogen fuel cells for space and underwater applications, and electrolysers that produce hydrogen and oxygen from water directly at 2,000 psi pressure without need for a mechanical compressor. In 2022, we began our first production contracts based on these technologies, which begins to expand our role in the broader hydrogen economy…
