Abstract

The objective of this paper is to present the thermal recovery system of the MYRTE hydrogen chain. This system recaptures the thermal energy produced by the proton exchange membrane (PEM) fuel cell (100 kW) and a PEM electrolyzer (10 Nm3/h). The recovery system must insure to maintain the set point temperature of the inlet cooling water to the facilities. In that view, the heat is collected and stored in a water storage tank and the rest is dissipated using a turbofan. In this paper, the power dissipated and stored in the recovery system is evaluated based on measurements. The results show that the fuel cell generates at its maximal electrical power an equivalent amount of thermal power. Finally, a model coupling the fuel cell and the heat recovery system is implemented in TRNSYS®, showing a good agreement to the measurements.
