Abstract:A state-of-the-art anode-supported Ni-YSZ/YSZ/GSC/LSC SOFC with 16 cm2 cathode area was tested at low anodic flow rate (6.25 Ncc min−1 cm−2) and large excess of air (93.75 Ncm3 min−1 cm−2). These conditions are typical of stacks, where high H2 utilization is targeted, but are uncommon in single cell testing. H2-based mixtures were supplied between 550 °C and 750 °C, varying the partial pressure of H2 (between 93% and 21% with 7% H2O mol/mol) and H2O (between 10% and 50% H2O with 50% H2). I/V and EIS measuremen… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
