High-Temperature Hydrogen Recirculation Pump for Fuel Cell
January 08, 2020
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 […]
Corrosion-Resistant Scroll Hydrogen Blower
November 08, 2017
Alkaline Fuel Cells (AFC) are more efficient than Proton Exchange Membrane Fuel Cells (PEM) but use alkaline electrolytes that are difficult for standard pumping technologies because of their corrosive properties. Very few efficient, oil-free, and corrosion-resistant pumping options exist for this technology, and none are sized specifically for the needs of Alkaline Fuel Cells. Air […]

Providing 700 SLPM of air at 3 barg, […]
Spinning Scroll Compressor for H2 Recirculation
April 03, 2014
The P21H050A-BLDC-SH-SS is designed to boost 180 ºC, 100% humid hydrogen from 20 bara to 20.5 bara. Used to recirculate high-temperature hydrogen for a solid oxide fuel cell (SOFC) system in a weight-sensitive aerospace application, this innovative spinning scroll compressor provides 375 lpmv of hydrogen to the anode side of the SOFC in a package […]
Lightweight, Compact, Oil-free Scroll Compressor
February 07, 2013
Developed for mobile applications, the oil-free P24H056A-BLDC features a compact and lightweight design, capable of delivering up to 600 lpmv of air at 0.7 barg. The unit is ideal for mobile fuel cell and medical applications. The efficient compressor employs a traditional orbiting scroll design, but can operate at speeds over 4,000 RPM. While most […]
Fuel Cell Hydrogen Recirculation Pump
November 01, 2011
Weighing just 2.2 kg, the compact P16H034C-BLDC-SH delivers 100 lpm of hydrogen, with a 0.25 bard pressure rise. The semi-hermetic unit is designed to recirculate humidified hydrogen in fuel-cell-powered fork lifts. The goal of the project was to develop a semi-hermetic hydrogen pump that offers improved reliability and efficiency over diaphragm pumps currently used in […]
Stainless O2 and H2 Recirculation Pump
March 14, 2010
The stainless steel hydrogen and oxygen recirculation pump was developed for Lockheed Martin’s ISIS program as part of the on-board fuel cell system. Excess electricity provided by the photovoltaic cells during the day is used to convert water into oxygen and hydrogen, which is used by the fuel cell system to power the dirigible during […]
