Fuel cell system with liquid organic hydrogen carrier system

Abstract

A system comprising a fuel cell, a coolant circuit, and a dehydrogenation reactor for a liquid organic hydrogen carrier (LOHC). The fuel cell has an operating temperature about, or less than, an operating temperature of the dehydrogenation reactor. The coolant circuit is configured to circulate a coolant from a heat-exchanger of the fuel cell through a temperature lift stage to a heat-exchanger of the dehydrogenation reactor. The temperature lift stage of the coolant circuit is configured to raise the temperature of the coolant. A hydrogen-rich LOHC (LOHCRich) is passed through a pre-heating stage prior to the dehydrogenation reactor. The system is configured to transfer heat from the coolant in the temperature lift stage of the coolant circuit to the LOHCRich in the LOHC pre-heating stage.
