3.2.3. The Main Modalities to Energy Supply through Hydrogen Fuel Cell Technologies

The main types of fuel cell technologies presented above, having different operating characteristics and principles, can serve different segments of the energy generation market, either in CHP or power generation. Each type of technology has advantages and disadvantages that motivate its end use in specific applications and domains. In brief, the applications for which different types of fuel cells are suitable, but also their advantages and disadvantages, are presented in Table 3.


**Table 3.** Suitability in practical applications of the fuel cells types adapted from [68].

The main modalities of energy support of the stationary applications by hydrogen fuel cell technology that have been identified in the specialized literature refer to the following aspects:
