“…This phenomenon is introduced by the propagation of fuel and oxidant [22]. The delay that appears during the transient regime, generates a voltage Vr described in (1). Therefore, the implementation of the voltage Vr in the Nernst equation, as shown in Figure 1, allows to improve the FC model.…”

<p><span lang="EN-GB">In this paper, a new dynamic model is presented of the proton exchange membrane fuel cell (PEMFC), using energetic macroscopic representation (EMR). This model is developed for electric automotive applications, powered by a hybrid energy storage system (HESS). The PEMFC can be used as a primary source, the supercapacitors (SC) and/or batteries are the secondary sources. The model design enables the optimization of energy use and the reduction of equipment costs, by involving the fuel cell (FC) in the transient regimes. This model takes into consideration dynamic phenomena, such as double layer capacitance, charge transfer, energy losses caused by the propagation fuel and oxidant delay. The new developed model has been tested and validated using BAHIA bench of HELION/AREVA.</span></p>

“…However, due to the complexity and heavy calculative load of these models, they are not suitable for control designs (Amphlett et al 1994;Ge & Yi 2003;Yu et al 2005). Besides that, the mathematical model for PEMFC stack system level model in literature are developed at the cell level and include spatial variations of the fuel cell parameters (Sharma et al 2015;Zhong & Li 2016;Enearu et al 2017;Jiao et al 2017). A simplified mathematical model is required to operate the PEMFC system at optimal conditions and maintain a high performance of the PEMFC system.…”

Generally, it is possible to reduce the size, cost, and parasitic loss of polymer electrolyte membrane fuel cell (PEMFC) system with an air-cooled system, open cathode and self-humidifying stack for portable fuel cell application. In order to ensure the that PEMFC stack applicable for portable fuel cell application, a mathematical model is useful tool for saving design cost, giving a better system design and operation. Therefore, this study is focused on developing a simplified zero-dimensional mathematical model for self-humidifying and open cathode 200W PEMFC stack for portable fuel cell generator application. The mathematical equations are modelled by using Matlab-Simulink tools in order to simulate the operation of the developed mode. This simulation is then compared to a commercially 200W Horizon PEMFC stack (H-200) for data validation purposes. The air inlet flow rate is chosen to test the sensitivity of the fuel cell stack model. The air inlet stoichiometry of 2, 5, 20, and 50 was varied to generate a different air inlet flow rate. Based on the simulation, air inlet stoichiometry above 15 is sufficient to produce a high output stack voltage. However, in a real operation of the H-200 fuel cell stack system needs air inlet stoichiometry at about 20 because a fan is used to supply air and also the cooling system. High anode and cathode relative humidity result in a high output stack voltage. However, it is better to increase the anode relative humidity than cathode relative humidity to get high output stack voltage. ABSTRAK Umumnya, dalam aplikasi penjana sel fuel mudah alih, ia adalah berkemungkinan untuk mengurangkan saiz, kos, dan kehilangan parasit sel fuel polimer membran elektrolit (PEMFC) dengan menggunakan sistem penyejuk udara, jenis katod terbuka dan pelembapan-kendiri. Bagi memastikan tindanan PEMFC sesuai bagi aplikasi penjana sel fuel mudah alih, model matematik merupakan pendekatan yang sesuai bagi menjimatkan kos reka bentuk serta menghasilkan reka bentuk dan operasi sistem yang lebih baik. Oleh itu, kajian ini tertumpu kepada pembangunan model matematik sifar dimensi bagi pelembapan-kendiri dan katod terbuka tindanan PEMFC 200W bagi aplikasi penjana kuasa sel fuel mudah alih. Persamaan matematik dimodelkan dengan menggunakan Matlab-Simulink bagi mensimulasikan model matematik yang dibangunkan. Hasil simulasi ini dibandingkan dengan hasil uji kaji tindanan 200W Horizon PEMFC (H-200) komersil bagi tujuan pengesahan model matematik. Kadar alir masuk udara dipilih untuk menguji sensitiviti model tindanan sel fuel. Oleh itu, stoikiometri inlet udara dari 2, 5, 20, dan 50 disimulasi untuk menghasilkan kadar alir masuk udara yang berbeza. Berdasarkan hasil simulasi, stoikiometri inlet udara di atas 15 adalah mencukupi untuk menghasilkan voltan tindanan sel fuel yang tinggi. Walau bagaimanapun, dalam pengoperasian sebenar, sistem tindanan sel fuel H-200 memerlukan stoikiometri inlet udara sekitar 20 kerana kipas digunakan untuk membekalkan udara dan juga sistem penyejukan. Kelembapan relatif anod da...

With the growing energy crisis and environmental problems in recent years, the green energy technology represented by fuel cell technology has been developing rapidly. Since air contains a large amount of nitrogen that does not participate in the reaction, the circulation of nitrogen in the cathode gas supply system will increase the power consumption of the air compressor, resulting in a lower net power output of the fuel cell system. In order to improve the output performance of the fuel cell system, a new fuel cell cathode gas supply system with oxygen and air mixing is proposed in this paper, and the research results show that this topology can effectively increase the output power of the stack and reduce the power consumption of the air compressor, which can eventually increase the net power of the system to more than 10%. This study provides an effective theoretical guide for the design of fuel cell system and the optimal matching of cathode gas supply system.
