Abstract: A method for the rapid production of electrode structures such as Cu-SDC anodes for use in direct oxidation solid oxide fuel cells involves co-depositing a copper-containing material and a ceramic by plasma spraying to form a coating on a substrate. Layers of CuO-SDC have been co-deposited by air plasma spraying, followed by in-situ reduction of the CuO to Cu in the anodes. Materials having catalytic properties, such as cobalt, may also be incorporated in the structures. Controlled compositional or microstructural gradients may be applied to optimize the microstructure and composition of the coatings.

Abstract: A respiration feedback monitoring and feedback system, and in particular, an apparatus and corresponding method for monitoring and controlling respiration activity of a user that encompasses a respiration monitor sized and configured to be worn by the user. The respiration activity of the user is measured with components including a signal generator and a self-retaining belt which coils and uncoils within housing. Feedback is provided to the user using non-audible or audible signals, such as vibrations of certain duration and repetition or music players. A method for determining appropriate feedback corresponding to the user's respiration activity is also provided. The method includes defining the user's desired respiratory activity and respiration feedback criteria for the determination of the appropriate feedback. The method further includes various user selectable operational variables.
