Abstract
A gas-to-power (GtoP) system for power outages is digitally modeled and experimentally developed in this work. The
design includes a solid-state hydrogen storage system based on TiFeMn as a hydride forming alloy (5 tanks, total
capacity: 110 g H2) and an air-cooled fuel cell (maximum power: 1.6 kW). In an emergency use case of the system,
hydrogen is supplied to the fuel cell, and the waste heat coming from the exhaust air of the fuel cell is used for the
endothermic dehydrogenation reaction of the metal hydride. This GtoP system shows fast, stable, and reliable
responses from 149 W to 596 W under constant and dynamic conditions. The developed model is based on a network
approach, and it is validated under static and dynamic power load scenarios, showing excellent agreement with the
experimental results
