Internal water management in proton exchange membrane (PEM) fuel cell has been considered as one of most significant key factors for its performance enhancement. It is because relative humidity of hydrogen and air is strongly related to the performance of PEM fuel cell in terms of H+ movement within the membrane. In addition, production of H2O by chemical reactions can bring several problems during concentration loss region since combination of vapor in supplying air and byproduct of chemical reaction should lead to excess H2O remaining in PEM fuel cell, resulting flooding phenomena which may block air flow channels. Therefore, in order to understand and manage such phenomena to enhance the performance of PEM fuel cell, especially under concentration loss region, this paper focuses on the visualization of the flooding phenomena and application of the modified flow path on the cathode separator for flooding reduction.

This paper presents a three-dimensional transitional model to describe an innovative design for an air-breathing proton exchange membrane fuel cell (AB-PEMFC) with a microdiaphragm actuated by a piezoelectric device. This newly designed gas pump with a piezoelectric actuation structure is utilized as an air-flow channel in a proton exchange membrane fuel cell (PEMFC) system called PZT-PEMFC. When the actuator moves in the outward direction to increase the cathode channel volume, the air is sucked into the chamber: inward movement decreases channel volume and thereby compresses air into the catalyst layer and enhances the chemical reaction. The air-standard PZT-PEMFC cycle coupling with fuel∕air ratio is proposed to describe an air-breathing PZT-PEMFC. The model is able to simulate its major phenomena and performance in different fuel∕air ratio and PZT frequency. The results show that the PZT actuation leads to a more stable current output, more drained water, stronger suction, and overcome concentration losses at a proper PZT frequency.
