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.
Pem fuel cell dimensions.
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 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.
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.
Just like batteries individual cells are stacked to achieve a higher voltage and power.

Typical polarization curve for a pem fuel cell stack.
This assembly of cells is called a fuel cell stack or just a stack.
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.
