Title:
ELECTROLYTE SUPPLY UNIT OF MATRIX TYPE FUEL CELL
Document Type and Number:
Japanese Patent JPS61107667
Kind Code:
A
Abstract:

PURPOSE: To safely, simply, smoothly supply liquid electrolyte to a matrix of a unit cell by arranging an electrolyte storage tank in a higher place than a matrix.

CONSTITUTION: When electrolyte is supplied to an electrolyte supply pipe 16, the electrolyte drops and is filled in each storage tank 9 from an opening 13. By grooves 12 on the top of a separating plate 11, all storage tanks are filled with electrolyte. When electrolyte is additionally supplied, an electrolyte level reaches the upper end of an electrolyte exhaust part 7. The excess amount of electrolyte overflows from an exhaust part 15 and is supplied another storage tank 9 located in the lower part. When supply of the electrolyte stopped, the electrolyte in the storage tank 9 is supplied to a matrix 3 in each unit cell 1 from an electrolyte supply pipe 8. Electrolyte pressure applied to each unit cell is generated by water head caused by height difference between the matrix 2 and the storage tank 9. By adjusting the water head, apply of excess electrolyte pressure to a unit cell located in the lower part of a cell stack can be prevented.
