Applications Overview

We have provided solutions to help solve problems for some of the earliest fuel cell systems globally. Ensuring exceptional performance and durability of our pumps, we are continually partnering for the next generation of technologies. Micropump pumps have been integral components of systems from hydrogen generation technology to fuel cell systems for transportation, residential power, back-up power, micro-CHP or ancillary systems. By partnering with us, you can leverage our decades of pump experience to achieve tailored fuel cell technology for vehicular or distributed power.

Micropump application engineers provide guidance in design and can work with you for customized component parts to optimize your system reliability. We have collaborated with technology leaders to improve various aspects of the fluid handling stages. From reformer efficiency through high differential pressures or initiating immediate fluid movement in the system based on control inputs, Micropump has delivered compact but robust designs. Micropump’s precision fluid movement includes handling water balance concerns of flooding or too dry conditions in the fuel cell stack. Due to our uniform and accurate flow rates, humidity management in the membrane is better controlled and more stable. The Micropump cavity and suction shoe gear style design also delivers high pressures for greater reformer efficiency and an isolated fluid path with no leak-prone dynamic seals.

When designing systems to power the future, choose Micropump as your partner.
