...Tatsumi Ishihara; Jingwang Yan; Makiko Enoki; Sachio Okada; Hiroshige Matsumoto Intermediate temperature solid oxide fuel cells (SOFCs), which are highly tolerant against a thermal cycle, are studied by using the Ni–Fe porous alloy substrate prepared by an in situ reduction. It was found that Ni–Fe...

...T. Franco; Z. HoshiarDin; P. Szabo; M. Lang; G. Schiller In the thin-film solid oxide fuel cell (SOFC) concept of the German Aerospace Center (DLR) in Stuttgart, the entire membrane electrode assembly (MEA) is deposited onto a porous metallic substrate by an integrated multistep vacuum plasma spray...

... of the processing route and the microstructure of La 0.65 Sr 0.3 MnO 3 (LSM) and La 0.58 Sr 0.4 Co 0.2 Fe 0.8 O 3 − δ (LSCF)-type SOFCs. In the case of the LSM-type single cells, the following aspects relating to the electrochemical performance were investigated in more detail: (1) production of the anode substrate...

... as the production process for anode substrates. Results from electrochemical measurements performed between 700 and 900 ° C with H 2 ( 3 vol % H 2 O ) as fuel gas and air as the oxidant showed that performance increased with increasing grain size of the outer cathode current collector layer: the highest performance...

... had a compression of ∼ 400 MPa in the c-ScSZ electrolyte thin film and a tension of 50–100 MPa in the NiO-YSZ anode substrate at room temperature. The internal stress decreased with increasing temperature, becoming approximately zero at 1000 K. Although the internal stress returned to its initial...

...D. Gruber; N. Ponath; J. Müller A plasma polymerization process for preparing proton-conducting electrolyte membranes from tetrafluoroethylene and water is presented. They can be deposited on different substrates, e.g., gas diffusion layers or as barrier layers on other polymer electrolyte...
