Beschreibung
Zusammenfassung:	A microfibrous fuel cell structure of elongated form with a longitudinal axis. Such microfibrous fuel cell includes electrocatalyst layers supported by a fiber network formed of unidirectional or substantially unidirectional conductive fibers. The conductive fibers of such fiber network are oriented parallelly or substantially parallelly to the longitudinal axis of the fuel cell, therefore allowing such fiber network to conform to the curvature of the microfibrous fuel cell along the radial direction but without causing overbending of the individual fibers.
