Criticality and Life-Cycle Assessment of Materials Used in Fuel-Cell and Hydrogen Technologies

The purpose of this paper is to obtain relevant data on materials that are the most commonly used in fuel-cell and hydrogen technologies. focus polymer-electrolyte-membrane fuel cells, solid-oxide water electrolysers alkaline electrolysers. An innovative, methodological approach was developed for a preliminary material assessment four This leads more rapid identification influential or critical substantially increase environmental impact also assisted amassing life-cycle inventories—the emphasis here technology because it still its early development stage thus has deficient materials’ database—that were an in-depth material-criticality analysis. All listed materials—that either could potentially be these technologies—were analysed give important information industries, recycling industry, economy, as well policymakers. main conclusion from have highest impacts; lower impacts seen cells while lowest observed results presented together all considered materials, but separately each technology.
