Horizon H-Series stacks are open-cathode PEM fuel cell systems with power envelopes ranging from 12-5000W. These systems are easy to install and move thanks to being small and light-weight while offering fast start-up and quick response times. Because of these benefits they can be efficiently integrated into various application systems. H-Series stacks are designed for use in applications like robots, small cars, boats or bicycles. Normally the systems are not possible to connect with computer but on demand we can provide adjusted controller with RS232. Systems producing sixty watts or higher come with a LCD display, and monitoring software is also available. The LCD screen and monitoring software display the voltage, current and temperature of these systems. Additionally, we can offer tailor-made DC/DC converters.
