“…Recently, the rapid advancements in portable micro-electronic devices (e.g., mini laptops, micro biosensors, and mini unmanned aerial vehicles) have created urgent requirements to assemble a micro power source with high power density, long duration, and low cost [1][2][3]. Fuel cells serve as a highly efficient electrochemical reaction energy conversion device, which provides a promising solution to support the power of these micro-electronic devices [4][5][6]. As a kind of micro fuel cell, air-breathing proton exchange membrane fuel cells (PEMFCs) are fed by hydrogen from a micro hydrogen tank and oxygen from the air [7,8].…”

Air-breathing proton exchange membrane fuel cells (PEMFCs) show enormous potential in small and portable applications because of their brief construction time without the need for gas supply, humidification and cooling devices. In the current work, a 3D multiphase model of single air-breathing PEMFCs is developed by considering the contact resistance between the gas diffusion layer and bipolar plate and the anisotropic thermal conduction and electric conductive in the through-plane and in-plane directions. The 3D model presents good grid independence and agreement with the experimental polarization curve. The single PEMFC with the best open area ratio of 55% achieves the maximum peak power density of 179.3 mW cm−2. For the fuel cell stack with 10 single fuel cells, the application of the anode window flow field is beneficial to improve the stack peak power density compared to the anode serpentine flow field. The developed model is capable of providing assistance in designing high-performance air-breathing PEMFC stacks.
