Uniquely designed for high-temperature mixed gas hydrogen production, the P13H032A-BLDC-SH semi-hermetic scroll compressor incorporates several innovations in one versatile fuel cell recirculation pump.
State-of-the-art fuel cell stacks run most efficiently on pure hydrogen (H2); however, clean supply is often economically prohibitive. To solve this, the Department of Energy has invested in several pilot projects to accelerate the development of on-demand electrolysis H2 fuel separation from humid mixed-gas streams, including natural gas (CH4), syngas, and others for direct use in mobile and stationary fuel cell applications. High-temperature (above 120 ⁰C) humid gases are necessary to increase the efficiency of the fuel cell and reduce contaminate deposition on catalyst surfaces. To meet the need for next-generation solid oxide electrolyzer cell (SOEC) fuel production, Air Squared has devloped the semi-hermetic P13H032A-BLDC-SH scroll recirculation pump, capable of handling high-temperature, humid, mixed gases.
Designed from the ground up for use with most hydrogenated gases, the P13H032A-BLDC-SH integrates several patented innovations. The high-clearance involutes control thermal expansion during compression, maintaining efficiency while mitigating catalyst deposition. An integrated liquid-cooled motor protects the internal componentry from burn-out while handling the high-temperature gases. The lightweight, compact scrolls sit within an oil-free semi-hermetic housing, mitigating leakage and safety hazards when pumping H2. The high-temperature drivetrain geometry prevents seizure, while the isolated bearings and motor resist corrosion.
