Drive cycle simulations. The information generated by the MHSDT was used in conjunction with the metal hydride dehydrogenation kinetics to estimate the performance of a fuel cell-powered LDV with a metal hydride storage system. The Vehicle Framework Model (VFM) simulates the dynamic performance of the vehicle and storage system. For these simulations the EPA US06 was used, which is an aggressive LDV drive cycle (Figure ). The model assumes that the vehicle can begin driving immediately.
