Objectives • Develop the concept of a solid oxide fuel-fed electrolysis cell (SOFEC) for hydrogen production. • Identify and develop SOFEC cathode materials that are electrocatalytically and chemically stable in both reducing and oxidizing atmospheres. • Develop a novel concept of a composite/hybrid planar SOFEC-solid oxide fuel cell (SOFC) stack to co-generate hydrogen and electricity. • Demon...

Sampled-data controller is presented for solid oxide fuel cell systems which is expressed by a sector bounded nonlinear model. The proposed control law is obtained by solving a convex problem satisfying several linear matrix inequalities. Simulation results are given to show the effectiveness of the proposed design method. Keywords—Sampled-data control, Sector bound, Solid oxide fuel cell, Time...

Abstract Solid-state electrochemistry (SSE) is an interdisciplinary field bridging and solid-state ionics deals primarily with the properties of solids that conduct ions in case ionic conducting solid electrolytes electrons and/or electron holes mixed electronic materials. However, devices such as oxide fuel cells (SOFCs), there are unique electrochemical features due to high operating temperat...

Mn(1.5)Co(1.5)O(4) spinel oxide as a cathode or one component of a composite cathode presents no visible reaction with an Y(2)O(3)-stabilized ZrO(2) electrolyte. The low electrode polarization resistances and good performance compared with traditional Sr-doped LaMnO(3)-YSZ composite cathodes imply promising application for the next generation of intermediate-temperature solid oxide fuel cells.
