This spotlight focuses on materials for proton exchange membrane pem fuel cells also referred to as polymeric electrolyte membrane fuel cells which operate at relatively low temperatures 80 c.
Pem fuel cell parts.
The parts of a pem fuel cell the polymer exchange membrane fuel cell pemfc is one of the most promising fuel cell technologies.
Bipolar plates constitute one of the most important parts of a pem fuel cell stack with multifunctional character.
The pemfc uses one of the simplest reactions of any fuel cell.
First let s take a look at what s in a pem fuel cell.
Proton exchange membrane pem is one specific fuel cell technology that is highly suited to automotive applications due to its energy conversion efficiency and package compactness.
It distributes fuel gas and oxygen over the whole.
It conducts the electrons that are freed from the hydrogen molecules so that they can be used in an external circuit.
Pem fuel cells are made from several layers of different materials.
The most common type of fuel cell and the one most people think if first is the polymer electrolyte membrane or proton exchange membrane pem fuel cell.
The development of new component materials with increased performance and cost effectiveness is a critical part of emerging fuel cell research.
The anode the negative post of the fuel cell has several jobs.
Because they are lightweight have such high power density and cold start capability they qualify for many applications such as stationary.
Polymer electrolyte membrane pem fuel cells are the current focus of research for fuel cell vehicle applications.
Proton exchange membrane or pem fuel cells are considered to be the most versatile type of fuel cells currently in production.
A pem fuel cell has 4 components.
This type of fuel cell will probably end up powering cars buses and maybe even your house.
They produce the most power for a given weight or volume of fuel cell.
These cells run on hydrogen at fairly.
The main parts of a pem fuel cell are described below.
