Abstract:
1. A method of continuously producing multiple layer fuel cell assemblies, comprising: processing a web of membrane material having first and second opposed major surfaces, a first bonding web having first and second opposed major bonding surfaces, and a first web having first and second opposed major surfaces comprising fluid transport layer (FTL) material to form a first surface of a membrane electrode assembly (MEA) web; processing the web of membrane material having first and second opposed major surfaces, a second bonding web having first and second opposed major bonding surfaces, and a second web having first and second opposed major surfaces comprising FTL material to form a second surface of the MEA web; providing first flow field plates; providing second flow field plates; and encasing each MEA of the MEA web between a respective pair of the first and second flow field plates; wherein a portion of the first major bonding surface of the first bonding web serves to facilitate adhering contact between a portion of the second major surface of the first web comprising FTL material; wherein a portion of the second major bonding surface of the first bonding web serves to facilitate adhering contact between a portion of the first major surface of the web of membrane material; wherein a portion of the first major bonding surface of the second bonding web serves to facilitate adhering contact between a portion of the second major surface of the web of membrane material; and wherein a portion of the second major bonding surface of the second bonding web serves to facilitate adhering contact between a portion of the first major surface of the second web comprising FTL material.
