In this paper, we discuss the design and performance of a low cost, fully integrated power conversion and control system for a modified Global Electric Motors (GEM) fuel cell hybrid vehicle. The need for a custom converter and control system has become apparent as the commercial DC-DC market seems to have a void in the ranges of power and voltage required for fuel cell vehicle applications. The system incorporates a custom designed DC-DC boost converter which steps up the nominal 26 VDC fuel cell stack voltage to interface with the 72 VDC vehicle battery bus at an input power level of 1.2 kW. Additionally, several embedded control functions are implemented to integrate a Ballard Nexa™ fuel cell power module into the GEM vehicle. Design equations supported by preliminary performance data indicates that the DC-DC power converter achieves a conversion efficiency approaching 98% for a single fuel cell power module operating at full output power (1.2kW). The high efficiency allows for a simple and flexible air-cooled design with minimal heat sink requirements and cooling system weight. The control system incorporates algorithms to perform battery charging and power ramp rate, as well as fuel cell voltage, and current limiting algorithms. The control system exhibits stable performance characteristics throughout the entire vehicle load range and battery state of charge range, while tracking vehicle transient conditions.

Power converter with full closed loop water cooling system, works not only use water cooling characteristics of high efficiency, but also the electricity, and reducing the volume to prevent contamination. In this paper, we proposed a novel p-cycle safety protection approach that can provide rapid cycling radiating, and can restore the status of power device. For power cabinet composition, IGBT power modules and reactors is primarary radiating components, in which IGBT power modules that used for water cooling solution is modeled as the cooled automobile engine cooling system using cycling design principle. Besides, machine side and the network side of the power module is installed in separate cabinet to improve the tightness of the entire cabinet, in order to resist sandstorms.

Low Carbon

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.

Stack Model

Fuel cell systems are regarded as a promising candidate in replacing the internal combustion engine as a renewable and emission free alternative in automotive applications. However, the operation of a fuel cell stack fulfilling transient power-demands poses significant challenges. Efficiency is to be maximized while adhering to critical constraints, avoiding adverse operational conditions (fuel starvation, membrane flooding or drying, etc.) and mitigating degradation as to increase the life-time of the stack. Owing to this complexity, advanced model-based diagnostic and control methods are increasingly investigated. In this work, a real time stack model is presented and its experimental parameterization is discussed. Furthermore, the stack model is integrated in a system simulation, where the compressor dynamics, the feedback controls for the hydrogen injection and back-pressure valve actuation, and the purging strategy are considered. The resulting system simulation, driven by the set-point values of the operating strategy is evaluated and validated on experimental data obtained from a fuel cell vehicle during on-road operation. It will be shown how the internal states of the fuel cell simulation evolve during the transient operation of the fuel cell vehicle. The measurement data, for which this analysis is conducted, stem from a fuel cell research and demonstrator vehicle, developed by a consortium of several academic and industrial partners under the lead of AVL List GmbH.

Fuel Cell Hybrid

In order to increase efficiency of the fuel cell vehicle, it can be hybridized by using batteries or ultra-capacitors. A fuel cell vehicle model is developed and validated by comparing the simulation results with real vehicle operating results from the Hyundai Tucson fuel cell hybrid vehicle. And various types of hybridization structure are compared by simulation and the effect of component sizing is also studied. In the vehicle model, the component and controller models were developed to have modularity and integrated to have forward facing characteristics. Thus, the hybrid controller is designed and optimized by using the simulation. This paper also presents the fuel economy of the developed fuel cell hybrid vehicle when it is operated on the chassis dynamometer.
