Sažetak
This work presents results of the development of hydrogen storage and supply system for electric forklift (STILL RX-60-30, 3 ton lifting capacity, 8O VDC bus voltage) equipped with a commercial low temperature PEMFC power module (GenDrive 1600-80A ; Plug Power). A new concept of the integration of the MH in the H2 storage system [1, 2], see Figure 1, has been realised. The system combines hydrogen storage in a composite gas cylinder (CGH2 ; part of the power module) and an MH extension tank thermally integrated with the power module. The MH tank comprises 20 externally liquid-heated-cooled MH containers filled with AB2-type hydrogen storage alloy characterised by H2 equilibrium pressures above 10 bar at T>20 dC. The MH container is built according to in-house solution [3] which provides easy activation of the MH material and fast H2 charge / discharge due to improved heat exchange performances. The combined CGH2+MH hydrogen storage system has the same storage capacity (~19 Nm3 H2) as the separate CGH2 tank charged at P=350 bar, but at a lower H2 charge pressure (~185 bar ; charge time about 15 minutes) allowing significant reduction in indirect costs associated with hydrogen refueling provided by a system (dispensing pressure 185 bar) which uses pipeline H2 (55 bar) available at the customer's site. The higher H2 dispensing pressure is provided by the integrated thermally driven MH H2 compressor. Both compressor and dispenser use services (steam, cooling water, compressed air, electricity) also available at the customer's site.
