With thousands of fuel cells sold worldwide, SFC Energy is the number one supplier of fuel cells. SFC fuel cells are intelligent power generators that can be used to continuously and fully automatically recharge batteries. EFOY Pro fuel cells are SFC Energy's industrial fuel cell series and have been developed especially to meet the needs of professional users. The EFOY Pro fuel cells are available in various performance classes, with outputs ranging from 45 W for small-scale power systems through to a 500 W module for UPS solutions. SFC Energy is a longstanding partner of MOBOTIX providing off-grid energy solutions for security and surveillance solutions. Those applications whether stationary or mobile surveillance require an independent, reliable and, ideally, noise-free power supply. Semi-stationary and stationary surveillance systems also need to be able to operate without interruptions in places where there is no mains connection.
