“…With the promotion of new power energy vehicles, the proton exchange membrane (PEM) fuel cells have attracted a lot of attention as a new type of automotive power source [1][2][3]. PEM fuel cells may replace the internal combustion engine to some extent with high power density, quick start-up, no pollution and low noise [4][5][6][7]. However, the actual application of PEM fuel cells has still many technical obstacles, which include research on PEM fuel cells water management [8][9][10][11].…”

“…Furthermore, one of the key points in water management is the coupling relationship between temperature and relative humidity . It is inevitable to keep the water and heat balance inside the fuel cells when different operating conditions , , . More importantly, the relative humidity (RH) as an important parameter connects with the heat transfer and the water balance has been attracted many researchers, but the respective study of anode relative humidity (ARH) and cathode relative humidity (CRH) still needs to be inproved, but the proper inlet gas relative humidity is beneficial to the uniformity of water content and the balance of heat inside the PEM fuel cells.…”

The relative humidity is an important parameter reflecting the performance of proton exchange membrane (PEM) fuel cells, which is often accompanied by changes in heat and temperature. In order to study the different humidification effects on the performance of PEM fuel cells, a temperature and heat transfer (T&HT) model is presented. The innovation of this paper is to study the performance of fuel cell (FC) from the perspective of temperature heat transfer by asymmetric humidification. Firstly, symmetrical humidification experiments are performed at three operating temperatures. After that, a three‐dimensional (3D) structure is built using fluent and T&HT model is imported through custom functions. Secondly, the asymmetric humidification experiment is put into practice with 60 °C operating temperature. Furthermore, the Taguchi method is used to optimize the performance of fuel cells in the crossover experiment. Finally, the experimental and numerical results are compared by the contours and polarization curves. The results show that T&HT model is in agreement with the experiment, and asymmetric humidification is more reasonable and flexible than symmetrical humidification. When the cathode relative humidity is 50% and the anode relative humidity is 75%, the maximum optimization rate of system efficiency is 17%.

Modeling of polymer electrolyte membrane fuel cell with circular and elliptical cross-section gas channels: A novel procedure

et al. 2018

Summary The main objective of this paper is to develop an analytical solution based on the perturbation method to solve the continuity and momentum equations governing the flow in gas channels of a PEMFC having circular and elliptical cross sections. The equations are solved in both the anode and cathode gas channels with appropriately defined perturbation parameters to obtain the velocity profile in these channels. It was observed that by changing the circular cross section to an elliptical one (ie, increasing the value of perturbation parameter), the axial velocity increases. As a result, the penetration of species into the reaction areas decreases. Then, the effect of species penetration speed on the performance of PEMFC is discussed. Increasing the penetration speed (ie, radial velocity) of the reactant gases causes the maximum value of the gas velocity in the channel to decrease. This would imply that the diffusion rate of the reactant species to the reaction areas, and thereby the cell performance would be optimized. Apart from the analytical solution, 3‐D numerical solution of the governing equations using collocated finite volume method along with the SIMPLE algorithm is also performed. The results are validated against the available published data. The numerical results confirm that by converting the circular cross section to the elliptical one, while other conditions are fixed, the PEMFC produces less current density.

Abstract:In order to study the influence of inlet gas humidification on the performance of proton exchange membrane fuel cell (PEMFC), a new inlet gas humidification efficiency (IGHE) model is proposed. Two parts including the water content of inlet gas humidification and the water content produced by electrochemical reaction consist of the total water content of PEM. The inlet gas humidification efficiency is derived. Firstly, the flow chart of calculation was given. Secondly, the experimental system was established and experiments had been done at the operating temperature of 70 ℃ and at 40% RH, 55% RH, 70% RH and 85% RH, respectively. Finally, the polarization curves of the IGHE model and experimental were compared and analyzed at 85% RH. The results show that the difference of experimental and IGHE model is minimum (0.03V) at 85% RH when the current density of PEMFC is 250 mA/cm 2 .
