PEM fuel cells can only use graphite based flow fields,it is true or false
Answers
In other words, PEM fuels cells only use flexible graphite based flow field.
It is actually the device used for enhancing water flow mechanism in water channels.
Due to many reasons, the channel might get blocked due to ice, which can lead to the degradation of the channel as well.
PEM fuel cells: It stands for Proton-exchange membrane fuel cells. It is also known as polymer electrolyte membrane fuel cells.
These type of fuel cells are developed mainly for transport application and portable fuel-cell applications.
Reasons:
The graphite plates are developed in various forms suited for different kinds of flow field in the fuel cell. The effect of flow field is a significant factor in determining the performance of the fuel cell.
The different flow field designs are used for oxygen and hydrogen while making graphite plates.
Enhances water flow mechanism in water channels.
Hence, PEM fuel cells can only use graphite based flow fields.
So, the given statement is true.
