Abstract
A fuel cell includes a flexible body and first and second fittings attached to the flexible body. The first and second fittings each include a first opening configured for ingress or egress of a fluid, and each include second openings extending through outer portions of the first and second fittings. The first and second fittings are more rigid than the flexible body. The fuel cell further includes a first elongated interconnect attached to the first fitting through one or more of the second openings extending through the outer portion of the first fitting and connected to the second fitting through one or more of the second openings extending through the outer portion of the second fitting such that the first elongated interconnect couples together the first and second fittings.
