Moving away from conventional solid oxide electrolytes, hybrid fuel cells based on composite electrolytes (a solid oxide electrolyte and a molten alkaline carbonate phase) exhibit promising performance due to the high electrolyte conductivity within the so-called intermediate temperature ranges (400-600 C). These electrolytes are a blend of those traditionally used in Solid Oxide and Molten Car...

In the present study, the operating conditions of an anode-supported high temperature direct internal reforming (DIR) planar solid oxide fuel cell (SOFC) are numerically analyzed. SOFCs are the energy conversion devices that produce electricity and heat directly from a gaseous fuel by the electrochemical combination of that fuel with an oxidant. A planar SOFC consists of an interconnect structu...

The operation of Fuel Cell Distributed Generation (FCDG) systems in distribution systems is introduced by modeling, controller design, and simulation study of a Solid Oxide Fuel Cell (SOFC) distributed generation (DG) system. The physical model of the fuel cell stack and dynamic models of power conditioning units are described. Then, suitable control architecture based on fuzzy logic contro...

There are substantial barriers to the introduction of hydrogen fuel cells for transportation, including the high cost of fuel-cell systems, the current lack of a hydrogen infrastructure, and the relatively low fuel efficiency when using hydrogen produced from hydrocarbons. Here, we describe a solid oxide fuel cell that combines a catalyst layer with a conventional anode, allowing internal refor...

Abstract-According to SECA program guidelines, solid oxide fuel cells (SOFC) will be produced in the form of 3–10 kW modules for residential use. In addition to residential use, these modules can also be used in apartment buildings, hospitals, etc., where a higher power rating would be required. For example, a hospital might require a 250 kW power supply. To provide this power using the SOFC mo...

This paper proposes novel Fuel Cell Auxiliary Power Unit (FCAPU) for J150+ aircraft application. The primary version of APU in J150+ aircraft is a gas turbine Auxiliary Power Unit (APU) which is based on gas turbine jet engine but in the suggested FCAPU, the generated electrical power is achieved from chemical energy with higher efficiency. The Solid Oxide Fuel Cell (SOFC) technology is used to...
