This paper describes a vehicle simulation toolbox developed under Matlab® environment, which can be used to estimate the range of a vehicle battery, or a fuel cell/battery hybrid system. The model is function of mechanical and physical variables that depend not only on the vehicle but also on the ground. This toolbox can be extended to GPS tracking files by means of reading data file plug-ins. Even standard drive cycles can be simulated. Battery and hydrogen consumption, hydrogen storage tank level, battery state of charge, power consumption and fuel cell energy production, maximum range and maximum number of cycles for a real route can be determined. The model facilitates the prediction of the vehicle range and the hydrogen and energy consumption. Real route simulation gives a good approximation of the vehicle speed close to real-life services instead of using driving cycles that are quite arbitrary approximations to a real route.

An efficient and systematic approach for finding the optimal operating conditions of hydrogen polymer electrolyte fuel cells has been developed by combining an efficient optimization method and a validated multi-resolution fuel cell simulation tool. Four control parameters including cell temperature, cathode stoichiometry, cathode pressure and cathode relative humidity are used to build the optimization objective, which is defined as the maximum overall efficiency of the fuel cell system under ideal or realistic system assumptions. Through the design of experiment method, a set of sample simulations are first carried out using the fuel cell simulation tool. An analytic metamodel is then constructed using the radial basis function approach based on the simulation results. A feasible sequential quadratic programming scheme is then employed to optimize the metamodel to achieve the global optimal solutions. The study shows that different optimal solutions exist for different system assumptions, as well as different current loading levels, classified into small, medium and large current densities. The approach adopted in this study is generic and can be readily applied to more control parameters and further to the fuel cell design optimizations.

Nowadays, we face a series of global challenges, including the growing depletion of fossil energy, environmental pollution, and global warming. The replacement of coal, petroleum, and natural gas by secondary energy resources is vital for sustainable development. Hydrogen (H2) energy is considered the ultimate energy in the 21st century because of its diverse sources, cleanliness, low carbon emission, flexibility, and high efficiency. H2 fuel cell vehicles are commonly the end-point application of H2 energy. Owing to their zero carbon emission, they are gradually replacing traditional vehicles powered by fossil fuel. As the H2 fuel cell vehicle industry rapidly develops, H2 fuel supply, especially H2 quality, attracts increasing attention. Compared with H2 for industrial use, the H2 purity requirements for fuel cells are not high. Still, the impurity content is strictly controlled since even a low amount of some impurities may irreversibly damage fuel cells’ performance and running life. This paper reviews different versions of current standards concerning H2 for fuel cell vehicles in China and abroad. Furthermore, we analyze the causes and developing trends for the changes in these standards in detail. On the other hand, according to characteristics of H2 for fuel cell vehicles, standard H2 purification technologies, such as pressure swing adsorption (PSA), membrane separation and metal hydride separation, were analyzed, and the latest research progress was reviewed.
