Low Temperature Electrolysis Benchmarking Protocols - Metadata

This dataset contains test protocols for characterizing and benchmarking Low Temperature Electrolysis (LTE) materials, components and sub-scale cells. LTE includes both proton exchange membrane (PEM) and alkaline exchange membrane (AEM) electrolysis. These protocols are intended to be used to facilitate benchmarking and direct comparison of test results between labs and other institutions, through verification of baseline data and testing setups. These test protocols are written in the format of a standard operating procedure (SOP). The dataset also contains a SOP that defines a standard set of definitions, metrics, units, and conventions for low temperature electrolysis (LTE). The goal is to ensure that the literature is consistent from research group to research group, and data is reported in similar formats, such that results can be compared on a similar basis.

The materials and the ex-situ properties characterized are: (1) membrane ionic conductivity, ion exchange capacity (IEC), gas permeation, chemical stability, alkaline stability, thermal stability, weight loss via thermal gravimetric analysis (TGA), high frequency resistance (HFR), chloride conductivity, water content or water uptake (2a) catalyst (Ir, iridium) activity, durability, oxygen evolution reaction (OER) activity via rotating disk electrode (RDE), electrochemical surface area (ECSA) via cyclic voltammetry (CV), (2b) Non-PGM or PGM-free catalyst electrical conductivity, two point measurement (3) gas diffusion layer (GDL) compressibility or compression
