Abstract
In Proton Exchange Membrane Fuel Cell (PEMFC) systems, an intercooler contributes to proper thermal management of the reactant air into the cathode. However, the structure/performance of it is not clear yet. In this paper, two case studies concerning an intercooler in a 100 kW PEMFC system are carried out. Plate-fin and tube-fin heat exchangers are analyzed as the intercooler, in terms of volume, pressure drop and weight, The ε-NTU method is used. As general characteristics of the intercooler, the volume is increased with system operating pressure, while the pressure drop is decreased due to the volume expansion. The plate-fin intercooler contributes to the weight reduction of the system because aluminum is used. However, at the high... (More)
In Proton Exchange Membrane Fuel Cell (PEMFC) systems, an intercooler contributes to proper thermal management of the reactant air into the cathode. However, the structure/performance of it is not clear yet. In this paper, two case studies concerning an intercooler in a 100 kW PEMFC system are carried out. Plate-fin and tube-fin heat exchangers are analyzed as the intercooler, in terms of volume, pressure drop and weight, The ε-NTU method is used. As general characteristics of the intercooler, the volume is increased with system operating pressure, while the pressure drop is decreased due to the volume expansion. The plate-fin intercooler contributes to the weight reduction of the system because aluminum is used. However, at the high operating pressure, space consumption is large. The tube-fin intercooler contributes to the volume reduction because the coolant is a liquid. However, the usage of stainless steel contributes to weight increase. The tube-fin intercooler in aluminum may contribute to space and weight reduction. However, a liquid coolant, which is proper for the PEMFC stack cooling without corrosion of aluminum, is needed.
