Abstract
Official abstract text for this publication.
The flow field plates in a bipolar plate assembly for a fuel cell can be both bonded and sealed appropriately using microencapsulated adhesives. This offers several advantages over using other adhesives which may have limited pot life and/or require lengthy curing periods at elevated temperature during which time the plates must be stably positioned and under compression.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for bonding and sealing a bipolar plate assembly for a fuel cell comprising: providing an anode flow field plate and a cathode flow field plate wherein the anode flow field plate comprises an anode flow field on one side, a coolant flow field on the other side, and a sealing surface on the coolant flow field side, and wherein the cathode flow field plate comprises a cathode flow field on one side, a coolant flow field on the other side, and a sealin…
