concerns stress the necessity of new solutions for energy supply both in the
stationary and automotive field. In this context, fuel cells emerged as an
interesting and promising solution, both for industrial and transport
these latter ones, high temperature PEM fuel cells systems are likely to be the
most versatile solution, due to the relative high level of operative
temperature, absence of water management problems, high tolerance to CO content
and flexibility in fuel composition. In comparison to conventional PEM fuel
cells, which require almost pure hydrogen and water as inlet fuel, this new
latter feature enables a wider range of possibilities in terms of fuel
composition, which consistently increase the flexibility of the system.
the different kind of fuel cells, high-temperature polymeric electrolyte
membrane (PEM) fuel cells operate typically at low temperature, in a range
within 120-200°C, and are thereby particularly suitable for automotive
applications. Compared to traditional low-temperature fuel cells, the
relatively high temperature significantly improves the cells' tolerance to CO,
making it advantageous to run this kind of fuel cells on reformate gas.
project will investigate the performance of a novel system coupling a 5 kW high
temperature PEM fuel cell fed by a hydrogen-rich reformate mixture. The system
is supposed to be employed as a battery-life extender for hybrid vehicles.
Several fuels will be investigated for the steam reforming process, such as
methanol, natural gas or ethanol. In
this work, the attention will be focused on the thermodynamic modeling, the
analysis of the different steady state systems and the comparison of the
different operative conditions and performances.
project will help to reproduce the behavior of a real setup, which is currently
under development for experimental tests.
