Fuel cells utilize an electrochemical process to convert the chemical energy in natural gas or pure hydrogen to electricity and heat. The process is non-polluting, low maintenance, and very quiet in operation. Large capacity fuel cells are now available to provide “clean” uninterrupted AC power for such critical installations as hospitals, computers, or for areas subject to frequent power grid fluctuations. These cells can operate in conjunction with, or independent of a commercial power grid, and are mostly used in place of fossil fuel powered generators. In one system, a fuel cell manufacturer uses two MTH T31, T41, or T51 Series pumps. One is a circulation pump which continuously filters the water supply and supplies the feed pump. The feed pump operates at 120 psi and injects de-ionized water into the process to produce the hydrogen necessary for the chemical to electrical energy conversion. The DI water usually requires pumps of all stainless-steel construction.

As fuel cell technology advances, and becomes viable for other applications, a very large new market is evolving and MTH is currently is pumps for a number of prototype fuel cell technologies. Two of our engineered products poised for this market, the ST21 (2,000 ~ 10,000 RPM DC brushless, variable speed seal-less canned turbine pump with a flow range up to 2 GPM and heads up to 500 feet), and its sister product, the SC31 (based on the same motor and controller, but features a centrifugal wet end and capacities up to 6 GPM) are designed specifically for DI water injection for fuel cells, and features a closed-loop pressure transducer feedback system to maintain tight control of system pressure.
