About Protonex Technology Corporation

Protonex is a leading provider of advanced fuel cell power solutions for sub-kilowatt portable, remote and mobile applications. Based on patented proton exchange membrane (PEM) and solid oxide fuel cell (SOFC) design and manufacturing technology, these power systems are among the industry’s smallest, lightest and highest performing fuel cell systems for portable power applications.

Protonex has developed several products designed for demanding military, commercial and consumer applications. These applications, which include man-portable power, portable emergency power, unmanned aerial vehicles, marine power and robotics, are areas of rapidly advancing technology with escalating power requirements that cannot effectively be met by traditional power sources. Protonex power solutions are designed to meet these requirements, extending runtimes and increasing performance while reducing overall size and weight.
