Storage Recommendations for Micro-Fuel Cells

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 in an inert oxygen-free atmosphere until the bag is opened.

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

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


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

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

3) Avoid any prolonged storage in warm or dry environments. Do not store the cells in an area that is exposed to direct sunlight.

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

5) Schedule stock cell orders to coincide with the expected need and thereby minimize cell storage periods. Although it is possible to store the cells for reasonably long periods and still maintain cell life, it is advisable to exercise strict discipline in this matter. For instance, set a stock period target of three months. By setting a goal to turn over stock every three months, cell life will be maximized and warranty issues minimized.
