The Yurok Tribe needed telecommunications access for the upper end of their Reservation, located in a deep and inaccessible canyon along the Klamath River. Their solution included a microwave repeater station on a remote mountaintop. The repeater ran on solar electric power, with a SERC fuel cell as an automated backup. The fuel cell operated in this application for nearly four years, accumulating over 7,000 hours of total run time. Landline telecommunications eventually replaced the microwave system, but the project provided the Tribe with a valuable interim solution and gave SERC a chance to test our technology in an unattended application operating under a wide and unpredictable range of conditions.
