In the area of analysis, a modeling tool for fuel cell vehicles needs to address the transient dynamic interaction between the electric drive train and the fuel cell system. Especially for vehicles with slow responding on-board fuel processor, this interaction is very different from the interaction between a battery (as power source) and an electric drive train in an electric vehicle design. Non-transient modeling leads to inaccurate predictions of vehicle performance and fuel consumption. When applied in the area of development, the existing programs do not support the employment of newer techniques, such as rapid prototyping. This is because the program structure merges control algorithms and component models, or different control algorithms (from different components) are lumped together in one single control block and not assigned to individual components as they are in real vehicles. In both cases, the transfer of control algorithms from the model into existing hardware is not possible. This paper is the first part of a three part series and benchmarks the 'state of the art' of existing programs. Several vehicle-modeling tools have been introduced and compared with each other. The compared models could be classified in two different groups. Hyzem and Psat as forward looking models and Advisor and Simplev in the group of backwards looking models. From a fundamental point of view none of the above models are satisfying. The investigated models compromise in a number of different areas, such as separation of control algorithms from component models and causality. As a result the models become difficult to understand, non-modular (even if they appear modular on the surface) and difficult to validate. Also, because of the number of compromises made, none of the investigated models appears suitable as a teaching instrument in companies or universities. Although this aspect is secondary for a professional use in industry, or in the policy area, it seems important that long-term suitable tools for teaching in the area of fuel cell vehicles are available. Based on this comparison a new fuel cell vehicle model is proposed in part II of this three part series.
