An autonomous hydrogen production system design based on the solid chemical hydride

Abstract

This paper develops a hydrogen generator prototype that is for fuel cell systems used in portable applications. This generator is designed based on the use of solid-state hydrides with high hydrogen storage capacity in the catalytic hydrolysis reaction. Some using problems such as unstable hydrogen production, one-off service life, heavy or large-volume storage system, and short duty time can be avoided in moveable applications when the use of the produced prototype. In addition, A simulation model and an autonomous control algorithm, which evaluates the hydrogen generation and temperature responses of the prototype, are developed. The results confirm that the performance of a portable and autonomous prototype with 4 parts and 1-hour hydrogen production capacity is enough for small fuel cell applications. As a result; the tightness and performance tests of the prototype were investigated using different catalyst samples for 1 hour, and the results were investigated in depth. The average flow rate of this 4-part autonomous generator is approximately 3.00 L/min.gcatalyst during 1 h. In the working cycle, the soft ripples have spied on the hydrogen-produced amount from time to time.
