Sažetak
Materials handling units / forklifts were identified as a promising early market for the development of the fuel cell business. Fuel cell powered forklifts, compared to the battery driven ones, lower the total logistics costs as they require shorter refuelling time and less maintenance. Due to necessity to provide low centre of gravity and sufficient weight of counterbalance for the safe operation, fuel cell forklifts can accommodate hydrogen storage systems on the basis of “low-temperature” metal hydrides without conventional limitation as to weight hydrogen storage density for vehicular applications. Metal hydride (MH) hydrogen storage as a BOP component of low-temperature fuel cell systems is characterised by compactness, flexibility and higher total system efficiency due to utilisation of the heat released during fuel cell stack operation [1]. The MH systems require lower refuelling and operating hydrogen pressures than commonly used gas cylinders thus providing more safe operation and requiring lower indirect costs for hydrogen refuelling infrastructure. Recently HySA Systems reported about integration of an MH extension tank in electric forklift (STILL-RX60-30L) with commercial PEMFC power module (GenDrive 1000 160X- 80CEA ; Plug Power Inc.) and development of a prototype lowpressure refuelling station with MH compressor for the refuelling of this forklift [2]. Since September 2015 both systems are in operation at Impala Platinum refineries in Springs, South Africa (Figures 1, 2). Since that time the systems are working without interruption, except for several short-time stops of the refuelling station for the service works. This work presents analysis of performance of the forklift and the refuelling station during their operation at the site of the industrial customer. On the basis of this analysis, HySA Systems has developed a prototype fuel cell power module (80 VDC in bus voltage, 10 kW in average electric power) for 3-ton lifting capacity STILL forklifts. The module has an integrated MH system which provides on-board storage of ~20 Nm3 H2 ; the refuelling time at H2 dispensing pressure of 185 bar is about 15 minutes.
