DYNAMICAL ANALYSIS VIA COMPUTER SIMULATION OF CATALYTIC MEMBRANE REACTOR FOR THE PRODUCTION OF PURE HYDROGEN IN FUEL CELLS APPLICATIONS

Résumé
In this work a mathematical model and a simulation of
transient behaviour of a single stage hydrogen
production-separation process for Proton Exchange
Membrane (PEM) Fuel Cell (FC) applications has been
performed. Methanol reforming process occurs in a
Catalytic Membrane Reactor (CMR) by REB Research
& Consulting filled with a commercial ZnO − CuO,
Alumina supported catalyst. Our Scope is to verify that
for a wide range of operating conditions, reactor
performance is kept at a sufficient level to produce
enough hydrogen to feed the fuel cell, in conformity
with manufacturer declarations, and also to provide a
detailed description of transient behaviour during load
regimes changes, start up and shut down of the system.
This model can run with thermal energy balance
equation to study an optimal heater tape wiring
diagram in order to obtain a suitable temperature
profile along the reactor. We obtain, with the use of the
CMR, the coupling of production-separation steps for
hydrogen at low working temperatures, were we
already get almost full methanol conversion in the first
part of the reactor.
