Loop Energy, Fraunhofer ISE testing shows eFlow tech can boost electrolyzers production

The application of Loop Energy’s proprietary eFlow technology in PEM electrolyzers has been verified by a third party.

Testing by the German Fraunhofer Institute for Solar Energy Systems ISE in collaboration with Fraunhofer USA has shown that a fuel cell architecture with a trapezoid flow field design can improve temperature uniformity. This bipolar plate architecture shows it can boost hydrogen output when incorporated into typical PEM electrolysis cells. In order to create a full-scale electrolyzer prototype for commercial validation, Loop Energy is currently looking for industrial partners.

Findings reveal that eFlow architecture, in comparison to typical flow fields with parallel channels, creates a more stable and consistent working environment in the PEM water electrolysis test cells, resulting in more hydrogen production and improved efficiency. Testing demonstrates that the more uniform working environment should favorably affect durability.

Loop Energy and Fraunhofer ISE are encouraging potential industrial partners to express interest in their work in response to the positive results. The advantages of eFlow for creating hydrogen on a commercial scale will be tested by interested parties working with the two businesses to design and produce an electrolyzer prototype. George Rubin, the chief commercial officer at Loop Energy, can receive any expressions of interest.

Today, Loop Energy’s fuel cell products use the company’s exclusive eFlow technology to provide unparalleled levels of fuel efficiency. Due to the more uniform current density and increased gas velocity made possible by its tapering channel design, eFlow offers greater thermal and water management. The potential application of the patented technology in the hydrogen energy sector is increased by the recent finding that eFlow can increase hydrogen production efficiency.

By the year 2051, the total cost of producing hydrogen is expected to increase by more than US$1 trillion. As a result, in order to meet the growing demand for hydrogen, both new and existing hydrogen producers are looking for a competitive advantage.
