| چکیده | ||
| در پژوهش حاضر، مدل سازی عددی پیل سوختی با الگوی جریان همسو و ناهمسو، به منظور بررسی میزان تأثیر متغیرهای عملیاتی بر عملکرد آن مورد توجه قرار گرفته است. در مدل در نظر گرفته شده، معادله های پیوستگی، اندازه حرکت، انتقال جرم، سرعت واکنش های الکتروشیمیایی و بار الکتریکی در طول کانال پیل سوختی پلیمری در سه بعد نوشته شده و به صورت همزمان با استفاده از روش عددی عنصر محدود حل شده اند. نتایج حاصل از مدل با داده های آزمایشگاهی ارائه شده در منابع پیشین تعیین اعتبار شدند. درمدل حل شده، تاثیر متغیرهایی همانند دما، فشار و طول کانال بر چگالی جریان الکتریکی الکترودها، میزان مصرف هیدروژن و اتلاف آن مورد بررسی قرار گرفته است. نتایج به دست آمده نشان میدهند که با افزایش دما از 60 به °C90 تحت شرایط ولتاژ ثابت، چگالی جریان کانال پیل سوختی پلیمری به میزان %19/4 افزایش می یابد. همچنین، با افزایش فشار از 1 به atm 5 در ولتاژ ثابت، چگالی جریان %26/9 افزایش پیدا می کند. علاوه بر آن، میزان مصرف هیدروژن در طول کانال با کاهش ولتاژ افزایش مییابد. | ||

| چکیده [English] | ||
| In the present study, a numerical model has been utilized to investigate the effects of operating parameters on the performance of a proton exchange membrane fuel cell in co-current and countercurrent patterns. The model considers the three-dimensional governing equations involve continuity, momentum, mass, electrode kinetics and potential fields across the channel of fuel cell. The coupled equations of the proposed model are then solved using the finite element method. The simulation results were validated with previous reported experimental data. In the results obtained from the model, the effect of variables such as temperature, pressure and length of channel on the current density of electrodes and the amount of waste hydrogen have been studied. It was found that at constant voltage, increasing the temperature from 60 to 90°C, raises the current density by 19.4%. At similar conditions, an increase in pressure from 1 to 5 atm, improves the fuel cell current density by 26.9%. In addition, with voltage drop across the channel, hydrogen consumption increases. | ||
