Solid oxide fuel cell able to miniaturize
Lamination technology that enables high electric power density without compromising power generation efficiency
Overview
Fuel cells are attracting attention as an environmentally friendly energy,
and various forms are being researched and developed. Solid oxide fuel
cells are focused from the energy efficiency perspective.
For a solid oxide fuel cell containing multi-cells, fuel and air are
supplied separately from the same direction to the anode and cathode
of each cell, which requires a fuel and an air supply unit, respectively. In
addition, since the solid oxide fuel cells have a structure in which a solid
electrolyte is sandwiched between an anode and a cathode, the fuel and
air supply system becomes complicated in order to supply them
separately to the anode and cathode which are close to each other. This
is the reason why the full cell miniaturization was difficult.
This invention is based on the structure of the electrode layer. By
separating the fuel and air input & output respectively, a smooth flow
can be achieved and the power generation efficiency can be improved.
