Failure analysis of Polymer Electrolyte Fuel Cells (PEFC)
conference contribution
posted on 2008-11-18, 17:02 authored by Pratap Rama, Rui Chen, J.D. AndrewsA qualitative FMEA study of Polymer Electrolyte Fuel Cell
(PEFC) technology is established and presented in the
current work through a literature survey of mechanisms
that govern performance degradation and failure. The
literature findings are translated into Fault Tree (FT)
diagrams that depict how basic events can develop into
performance degradation or failure in the context of the
following top events; (1) activation losses; (2) mass
transportation losses; (3) Ohmic losses; (4) efficiency
losses and (5) catastrophic cell failure. Twenty-two
identified faults and forty-seven frequent causes are
translated into fifty-two basic events and a system of FTs
with twenty-one reoccurring dominant mechanisms. The
four most dominant mechanisms discussed that currently
curtail sustained fuel cell performance relate to
membrane durability, liquid water formation, flow-field
design, and manufacturing practices.
