Abstract
The main purpose of this paper is to estimate primary energy saving of polymer electrolyte membrane fuel cell (PEM fuel cell) for a liquid desiccant indirect and direct evaporative cooling assisted 100% outdoor air system (LD-IDECOAS). Also, we have suggested the PEM fuel cell performance predicted model by experiments. The fuel cell system provides the electric power and thermal energy by combining hydrogen and oxygen simultaneously. If waste heat is used, the total energy efficiency of fuel cell is up to 85%. The PEM fuel cell is suitable as a system for supplying power and heat sources to LD-IDECOAS. Using the measured load profile of the pilot system, the required electric capacity of the fuel cell system was designed at 10 kW. To suggest the performance predicted model of fuel cell, several test were conducted in the facility of pilot system. The predicted model was used to calculate the annual primary energy saving of a fuel cell. In this research, the performance of the previous systems using conventional gas-fired boiler and purchased electricity are compared with that of the proposed system to evaluate energy saving potential.
