NDCPower offers PEM fuel cell stacks based on our proven Sequoia and Yosemite designs. We are looking to partner with automotive system integrators & automotive original equipment manufactures who are interested in exploring alternative suppliers of compact self humidify stacks that can operate at atmospheric pressure.
If you are interested in our technology, please contact us via the links on this page.
About NDC Stack Technology
Sequoia stacks offer conventional liquid-cooled configurations with external humidification. Yosemite stacks offer low-pressure and self-humidified operation for simplified physical plant requirements.
Customers that need a second source or plan to use existing physical plant systems will find the Sequoia series ideal.
Both Sequoia and Yosemite designs are available in power increments ranging from less than 1kW to over 15kW, depending on customer needs. Stacks are available as individual components or as modules that can be linked together for higher power applications.
Sequoia and Yosemite are rugged fuel cell stacks developed in Cheyenne, Wyoming at an altitude of over 1,800 meters. Sequoia and Yosemite stacks can be used for both motive and stationary power applications. They offer robust electrical power over a wide range of operating conditions.
