Abstract
A SOFC type fuel cell being small in size and large in output while providing good efficiency and being excellent in starting characteristics and load variation characteristics, is presented. A honeycomb type solid-oxide fuel cell is formed of a honeycomb structural body having square cell in cross section, wherein cells adjacent to wall surfaces constituting a fuel pole cell (a) function as air pole cells (b) and cells adjacent to the corners of wall surfaces of the fuel pole cell and adjacent to wall surfaces constituting air pole cell function as cooling air cells (c), whereby fuel pole cells, air pole cells and cooling air cells are arranged in longitudinal and lateral rows so that cells of the same type appear in every other location.
Claims12
A honeycomb type solid-oxide fuel cell formed of any of a solid-oxide material, a fuel pole material and an air pole material and having a honeycomb structural body comprising rectangular cells in cross section, wherein cells adjacent to wall surfaces constituting a fuel pole cell of the fuel cell function as air pole cells and cells adjacent to the comers of wall surfaces of the fuel pole cell and adjacent to wall surfaces of an air pole cell function as cooling air cells, whereby fuel pole cells, air pole cells and cooling air cells are arranged in longitudinal and lateral directions so that cells of the same type appear in every other location.
A honeycomb type solid-oxide fuel cell having fuel pole cells, air pole cells and cooling air cells which form a honeycomb structural body comprising square cells in cross section, said honeycomb structural body being made of any of a solid-oxide material, a fuel pole material and an air pole material, wherein a fuel cell group is formed by stacking at least two honeycomb type fuel cells in each of which cells adjacent to wall surfaces constituting a fuel pole cell of the fuel cell function as air pole cells and cells adjacent to the comers of wall surfaces of the fuel pole cell and adjacent to wall surfaces of an air pole cell function as cooling air cells, whereby fuel pole cells, air pole cells and cooling air cells are arranged in longitudinal and lateral directions so that cells of the same type appear in every other location, and fuel poles and air poles of the mutually adjacent honeycomb type fuel cells are connected with inter-connectors to form a series connection so that an electric power is taken by collectors provided at both ends of said group of the fuel cells.
