Abstract

This presentation discusses two technologies to reduce energy demand for Air-Conditioning in hydrogen fuel cell rolling stock by using waste energy. The hydrogen powered air-conditioning (HyPAC) utilizes the pressure work between tank and fuel cell and the absorption refrigerator uses the waste heat from the fuel cell. To analyse the feasability, the hydrogen mass flow, the waste heat flow and temperature constraints were analysed and design concepts for both were proposed.
