2.2.4 The Effect of Pressure

The Micro-Fuel Cell responds to the partial pressure of oxygen present inside the cell holder.

By design, the total gas pressure inside the cell holder is kept approximately the same as the atmospheric pressure. As the atmospheric pressure changes, the partial pressure of oxygen in the cell holder will change accordingly.

The impact due to changes in atmospheric pressure is usually limited to less than 3% of reading.
