Abstract: In this work, we present the design, fabrication and characterization of increased hydrogen storage capacity of the silicon based Chip Integrated Micro Polymer electrolyte membrane Fuel Cell Systems (CIµ-PFCS), to increase the run time. The increased hydrogen storage capacity is realized from the backside of the silicon wafer and filling (casting process) it with a newly developed advanced hydrogen storage material, palladium - polymer composite. The functionality, current-time measurements, hydrogen charging capacity and charging behaviour of the newly developed hydrogen storage technique in the CIµ-PFCS are investigated and presented in this work. The developed CIµ-PFCS with increased hydrogen storage capacity and advanced hydrogen storage technique shows a factor of 4 increased run time than the state-off-the-art CIµ-PFCS. The power density of the developed CIµ-PFCS was measured to be 2.1 [mW/cm²]. After a number of charging and discharging cycles of CIµ-PFCs with the presented hydrogen storage materials, proved to be long term stable. The advantage of the presented CIµ-PFCS is that there is an increased hydrogen storage volume on board and easy to fabricate with existing microsystem technologies.
