Storage Recommendations for Micro-FuelCells

After the Micro-fuel Cell barrier bag is sealed, the sensor (cell)continues to react with the oxygen inside the bag.

Eventually, all of the oxygen is consumed and the cell remains inan inert oxygen-free atmosphere until the bag is opened.

The barrier bag transmits negligible amounts of oxygen and othergases, and almost no moisture. Thus the cell can be stored forperiods up to 6 months and still provide 90% or better of itsexpected life when finally placed into use.

Loss of sensor life in storage can be minimized by following anumber of practical stocking procedures.


1) Never remove the cell from the barrier bag until the cell isready to be used.

2) Store the sealed cell in a cool storage chamber. Storagetemperature can be room temperature or below. A range of 10 to 22Celsius is satisfactory.

3) Avoid any prolonged storage in warm or dry environments. Do notstore the cells in an area that is exposed to direct sunlight.

4) Maintain careful records of the serial numbers for cells putinto stock and for those supplied out of stock. Cells should besupplied from stock on a first-in, first-out basis.

5) Schedule stock cell orders to coincide with the expected needand thereby minimize cell storage periods. Although it is possibleto store the cells for reasonably long periods and still maintaincell life, it is advisable to exercise strict discipline in thismatter. For instance, set a stock period target of three months. Bysetting a goal to turn over stock every three months, cell lifewill be maximized and warranty issues minimized.
