Fuel cell plate assemblies

A fuel cell plate assembly comprising:

• a bipolar plate comprising a port for receiving a fluid;
• a fluid diffusion layer;
• an electrode defining an active area;
• wherein the fluid diffusion layer comprises an extending region that is located outside of the footprint of the active area and extends between the port and the active area in order to communicate the fluid received at the port to the active area,
• the fuel cell plate assembly further comprising a first track of adhesive around the port, the first track of adhesive configured to provide a seal on the fuel cell plate assembly,
• wherein the first track of adhesive extends over the extending region of the fluid diffusion layer;
• and,
• wherein the bipolar plate comprises one or more fluid flow channels, and the fluid diffusion layer is configured to communicate the fluid received at the port to the one or more fluid flow channels.
