This study presents an experimental stack-level thermal and hydrodynamic assessment of a model air-cooled PEM fuel cell. To mimic the heat generation inside the MEA, rubber heater films are used. Pressure drop along the stack channels and temperature distribution on the bipolar plate surface are measured for the channel Reynolds number range of 200-500 and the stack input power range of 100-250...

Water transport in vapor/liquid form gas diffusion layers (GDL) of proton exchange membrane fuel cell (PEMFC) are numerically investigated this study. A stochastic method is employed to reconstruct the 3D structured GDL, then a validated phase change solver developed and implemented OpenFOAM platform simulate vapor condensation process. Comprehensive simulations carried out analyze GDL porosity...

In this paper, we experimentally investigated two high temperature polymer electrolyte membrane fuel cell (HT-PEMFC) stacks for their response to the presence of reformate impurities in an anode gas stream. The investigation was aimed at characterizing effects stack level, including humidified conditions and identifying fault features diagnosis purposes. Two HT-PEMFC 37 cells each with active a...

Silicon micro-hole arrays (Si-MHA) were fabricated as a gas diffusion layer (GDL) in a micro fuel cell using the micro-electro-mechanical-systems (MEMS) fabrication technique. The resistance temperature detector (RTD) sensor was integrated with the GDL on a bipolar plate to measure the temperature inside the fuel cell. Experimental results demonstrate that temperature was generally linearly rel...

Recent studies indicate that PEM fuel cell performance may be strongly influenced by in-plane permeability of the gas diffusion layer (GDL). The urrent study employs a radial flow technique for obtaining in-plane permeability of GDLs, using either gas or liquid as the impregnating fluid. A odel has been developed and experimentally verified to account for compressibility effects when permeabili...

A novel dual-imaging cisplatin-carrying molecular cargo capable of performing simultaneous optical and MR imaging is reported herein. This long-lasting MRI contrast agent (r1 relaxivity of 23.4 mM-1s-1 at 3T, 25 oC) is a photo-activated cisplatin prodrug (PtGdL) which enables real-time monitoring of anti-cancer efficacy. PtGdL is a model for monitoring the drug delivery and anti-cancer efficacy...

The dynamic behavior of liquid droplets on a reconstructed real gas diffusion layer (GDL) surface with the inertial effect produced by three dimensional (3D) flow channel is investigated using an improved pseudopotential multiphase model within unified lattice Boltzmann (ULBM) framework, which can realize thermodynamic consistency and tunable tension. microstructure GDL (Toray-090) including ca...
