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.
