PRESTAZIONI DI UNA FUEL CELL A SERVIZIO DI UN EDIFICIO CIVILE

Electricity demand is growing very strongly this is due to the increase in electricity consumption in the residential and industrial sector from the current relatively low levels. The building sector has been considered a relevant sector in which it is crucial to intervene to reduce energy consumption and related emissions. The reduction of greenhouse gas emissions in the building sector to a sustainable level will require tremendous efforts to increase both energy efficiency and the share of renewable energies. Apart from the lowering of energy demand through better insulation and fenestration, small combined heat and power (micro-cogeneration) systems may help improve the situation on the supply side by cutting both the non-renewable energy demand for residential buildings and peak loads in the electric grid. Fuel cells are one of the most promising technologies for delivering clean and efficient power for automotive and residential applications. In the recent years there was an increasing interest in fuel cell technology and fuel cells have reached a high development status. This development was mostly advanced by the automotive industry, because fuel cells are suitable to substitute the fossil fuels and also to provide an environment-friendly propulsion. But there is also a growing market for stationary fuel cell applications, e.g. for cogeneration of heat and power. Perfectly in line with the technological trend in place the main objective of this work is to describe and analyze a system for local generation of electricity and heat based primarily on a Fuel Cell with proton exchange membrane (PEM). This will show up as the efficiency of such a system could be much higher than that of traditional systems, particularly in light of the principle of co-generation of energy.
