Pem fuel cell dimensions.

A single fuel cell consists of a membrane electrode assembly mea and two flow field plates delivering about 0 5 and 1v voltage too low for most applications. Ht pemfc technology gives better flexibility with regard to the range of powers that can be supplied by the system which is directly related to the size of the fuel cell stack used. The global proton exchange membrane fuel cell pemfc market size was usd 0 91 billion in 2018 and is projected to reach usd 47 60 billion by 2026 exhibiting a cagr of 65 5 during the forecast period. Most fuel cell developers use a nominal voltage of 0 6 to 0 7 v at nominal power.

Pem is one of the furthest developed and most commonly used fuel cell systems. Proton exchange membrane fuel cell pemfc the proton exchange membrane also known as pem uses a polymer electrolyte. It powers cars serves as a portable power source and provides backup power in lieu of stationary batteries in offices. Proton exchange membrane fuel cells pemfc also known as polymer electrolyte membrane pem fuel cells are a type of fuel cell being developed mainly for transport applications as well as for stationary fuel cell applications and portable fuel cell applications their distinguishing features include lower temperature pressure ranges 50 to 100 c and a special proton conducting polymer.

Fuel cell systems can be designed at nominal voltages of 0 8 v per cell or higher if the correct design materials operating conditions balance of plant and electronics are selected.
