The laboratory has 02 German made Solo 161 Stirling engines. The first one (Figure 01) can operate with natural gas and PLG, and can be used to carry out performance tests, calculate the main parameters of operation such as electric efficiency and of cogeneration, fuel consumption, cooling water consumption, operation in variable loads, etc.

The other Solo 161 engine (Figure 03) has been adapted to operate coupled to a biomass gasifier and it operates from the combustion of the gases obtained in the gasification. This installation is pioneer in Brazil. From the tests of the system, it is meant to propose a pilot layout that could be operated in an isolated community in the North region of Brazil . This is one of the technologies with the greatest potential to reduce the consumption of fossil fuel and to contribute to the sustainable development of isolated communities of the country.

Also, in the Laboratory of Advanced Distributed Generation Systems, there is a 5KW solid oxide fuel cell (Figure 08) which operates with natural gas and can be adapted to operate with other fuels. This installation is the first of its type in Latin America , placing UNIFEI students in a privilege position in relation to those in other learning centers.
