      abstract     = {Proton exchange membrane fuel cells (PEMFC) are considered
                      an ideal solution for zero-emission vehicles. This study
                      focuses on the warm-up strategy of the PEMFC system in an
                      energy-type power train, which is widely used on city buses.
                      Firstly, a system model was built and validated by
                      experimental data. Based on the model, a dynamic programming
                      (DP) algorithm was utilized to determine a warm-up method
                      that optimizes global efficiency. Then, a rule-based
                      analysis was carried out and a three-step strategy based on
                      the DP algorithm was proposed in order to satisfy the demand
                      of real-time control. Simulation results show that the
                      efficiency optimization of the three-step strategy is very
                      close to that of the dynamic programming algorithm. In
                      addition, the effects of warm-up time and environment
                      temperature on efficiency are discussed. Results show that a
                      longer warm-up time and a higher environment temperature are
                      helpful for improving efficiency.},
