Development and testing of the fuel cell power module for 3-ton electric forklift

Previously, HySA Systems reported about integration of an MH extension tank in electric forklift with commercial (Plug Power Inc.) fuel cell power module [1-3]. This prototype is in operation at Impala Platinum refineries in Springs, South Africa, since September 2015. Here, we present 15 kWe fuel cell power module (as a replacement for the commercial one) which was developed and integrated by HySA Systems. The power module is built around commercial liquid cooled proton exchange membrane fuel cell (PEM FC) from Ballard. The fuel cell stack and DC to DC converter cooling loops are coupled with the integrated metal hydride hydrogen storage system in order to utilize released heat for hydrogen desorption. The fuel cell stack is electrically connected with seven 12V Pb-acid batteries connected in series, to achieve 84 V bus voltage. The fuel cell approach temperature (61 °C) is precisely controlled by means of two passive mixing valves and by variable controlled fan speed. The air after the scroll compressor is cooled down in the heat exchanger to prevent drying of the gas-to-gas humidifier membrane and to achieve required fuel cell approach temperature. Before final integration, each of the loops (water, hydrogen and air) were tested off- board to ensure that required control of each fuel cell input parameters such as hydrogen and air flow rates, pressures, temperatures and relative humidities were achieved. On the basis of the test results, the optimal control strategy has been elaborated. The work also presents preliminary results of off- board and on-board tests of the power module.
