Abstract
The main characteristic of autonomous power systems of radio repeaters is the duration of uninterrupted operation without maintenance. In existing schemes, autonomy is ensured by the use of solar panels, wind generators and batteries or diesel-generators. However, both batteries and diesel-generators in real practice suffer from many shortcomings and their use for autonomous operation is coupled with significant risks. Instead, they began to develop power supply devices for fuel cells. Typical fuel cells are significantly more expensive. But in recent years, solutions have appeared that lower cost, higher efficiency and, compared with diesel generators, greater fuel efficiency. The article describes these new installations and compares their main characteristics.

Keywords
