Biogas can be currently considered as an alternative option for electricity production, mainly due to its high energy content (hydrocarbon-rich source), its renewable status and its relatively low utilization cost. Solid Oxide Fuel Cell (SOFC) stacks convert fuel’s chemical energy to electricity with high efficiencies and reveal significant advantages on fuel flexibility combined with lower emi...

Fuel Cell power systems have important potential for many applications, both stationary and mobile, due to their outstanding energy efficiency and environmental characteristics [2]. In particular, Solid Oxide Fuel Cell (SOFC) systems emerge as one of the most commercially widespread technologies, together with Proton Exchange Membrane fuel cells (PEMFC), offering high energy efficiency and robu...

Protective coatings that resist oxide scale growth and decrease chromium evaporation are necessary to makestainless steel interconnect materials for long-term durable operation of solid oxide fuel cells (SOFCs). Inthis study a layer of manganese was coated on the surface of AISI 441 ferritic stainless steel which is used insolid oxide fuel cells for interconnect applications. The oxidation beha...

We propose a new comprehensive solution to global interconnect optimization. Traditional buffering algorithms mostly insert repeaters on net-by-net basis based slacks and possibly guided by wires. show how integrate routing congestion, placement timing constraints, power consumption, additional constraints into single resource sharing formulation. The core of our algorithm is buffered subroutin...
