Summary on Grant Application Form
This project aims to tackle inhomogeneity within a working fuel cell from the perspective of both the electrochemical engineer and the electrochemist, bya) producing membrane electrode assemblies (MEAs) using screen printing techniques with defined inhomogeneities such as sharp longitudinal boundaries between catalysed and non-catalysed regions;b) developing one or more fully instrumented test rigs, capable of characterising inhomogeneities within a working PEMFC over a range of length scales (m to mm) via the application of AC and DC based diagnostic techniques under steady-state and dynamic conditions; andc) developing a model of the fuel cell on a mesoscopic (mm) scale, allowing for inhomogeneities in microscopic parameters such as the electrocatalytic activity, diffusion coefficients, and conductivity.d) using the model to determine the sensitivity of fuel cell performance to heterogeneities on the m-mm scale.
