Water transport is critical to th operation and stability of polymer electrolyte fuel cells. Unfortunately, the physical mechanisms of water transport on porous fuel cell electrodes and flow channels are poorly understood. The object of this proposal is to employ combined theoretical and experimental approaches to identify the relevant physics of water transport in fuel cell electrodes. Several idealized experimental setups wll be made and studied using a micro-PIV system housed at the Queen's-RMC Fuel Cell Research Centre. These experiments will then provide guidance for the development of new multi-phase flow models suitable for simulating fuel cell performance using computational fluid dynamics. These models will then be available to guide the next generation of fuel cell designs and aid in the commercial viability of fuel cells.

水的传输对聚合物电解质燃料电池的运行和稳定性至关重要。 不幸的是，多孔燃料电池电极和流动通道上的水传输的物理机制知之甚少。 本提案的目的是采用理论和实验相结合的方法，以确定燃料电池电极中的水传输的相关物理。 几个理想化的实验设置将被提出和研究使用微型PIV系统设在皇后的RMC燃料电池研究中心。 然后，这些实验将提供指导的新的多相流模型的发展，适用于模拟燃料电池的性能，使用计算流体动力学。 这些模型将用于指导下一代燃料电池的设计，并有助于燃料电池的商业可行性。
