DCH/Enable^TM stationary fuel cells are optimized energy systems typically delivering from one to 10 kilowatts of clean electric power. Since the technology is scalable, higher-power outputs are readily obtained by expanding and integrating the number of proton exchange membrane (PEM) stacks (right).

Like the Enable^TM portable fuel cells, these large powerplants run on hydrogen — either directly in the form of a gas, or from a system-integrated reformer that generates hydrogen from a variety of common fuels, including natural gas and propane. Unlike our portable fuel cells, the system integrates several onboard pumps and motors used to move hydrogen and air within the system to enable higher levels of power.

Enable^TM stationary fuel cells offer proprietary advantages over competitive systems for applications in remote power, auxiliary power, back-up power, power quality, and more — including extremely fast response time, rapid start-up, internet connectivity, very high efficiency, and very low power requirements on stand-by.

Enable^TM engineers worked closely with a leading R&D organization for the world's power utilities to develop the fuel cell pictured on the right. Tied to the grid, it reacts virtually instantaneously to compensate for the varying loads — on the order of 75 microseconds — and thus serves as an excellent power quality system. It produces 3 kilowatts of electrical power (the design is scalable to higher wattages), delivered to a 200 VDC load, 400 VDC load, or 208 VAC line or load.

An Enable^TM 3kW unit delivered to the Texas Natural Resource Conservation Commission (displayed below) represents our second generation design — featuring fewer parts, fewer connections, and made rugged for moving by trailer to remote locations.

Our latest third generation design, recently introduced to the market, raises the bar in terms of its compact size, reliability and power density.
