SiGNa demonstrates hydrogen generation for portable fuel cells

SiGNa Chemistry has announced the successful design, assembly, and initial testing of its H300 Hydrogen Generation System. The H300 was demonstrated in collaboration with portable fuel cell developer Trulite Inc.

The H300 from SiGNa Chemistry utilizes real-time swappable cartridges that generate hydrogen on-demand using SiGNa’s proprietary sodium silicide (NaSi) powder. The H300 uses two hydrogen canisters that generate more than 800 liters of H2 at a combined flow-rate of up to 4 slpm (continuous) and 10 slpm (peak).

This level of continuous hydrogen flow supports a broad range of portable fuel cell applications, including backup power systems, emergency responder work-stations, military battery recharging, and electric bicycles. SiGNa has demonstrated hydrogen generation for applications ranging from 1 W to 500 W.

The H300 offers a real-time hydrogen fuel gauge, on-demand hydrogen generation, and rapid canister insertion/removal. In collaboration with Trulite Inc, a leading developer of portable and semi-portable hybrid power systems, SiGNa utilized the Trulite FCS-300 PEM fuel cell system to demonstrate the technology. The FCS unit delivers 300 W of continuous power, and has multiple electrical outputs.

‘Hydrogen storage continues to be the single most important piece of technology limiting portable fuel cell commercialization,’ says Ken Pearson, COO of Trulite. ‘High energy density, low cost, and start-stop capability are all critical market requirement areas that SiGNa’s NaSi powder technology has the potential to meet.’

‘The H300 platform provides the only high-performance, portable hydrogen generation system to the fuel cell industry,’ claims Andrew Wallace, Director of the Alternative Energy Research Center at SiGNa Chemistry. ‘This system will enable hydrogen fuel cell developers to readily evaluate sodium silicide and adapt their systems to be compatible with SiGNa’s technology.’
