thermal
management
system of PEMFC engine is designed.The emphasis is that the heat generated must be discharged quickly to maintain its isothermal operation.Then,based
on on
the
experiment,the effect of airflow rate and water flow rate
the performance of stack
is discussed.Lastly,according to the maximal stack output power,the maximal water flow rate is calculated,which provides water pumps
are a
theoretical basis for which type's radiators
or
used.
With
the development of automation is controlled
technology,it
is possible that the stack
salrle
operating temperature
automatically.At the
on
time,with
the
development of computer technology,simulation research system of PEMFC engine becomes
thermal
management
possible.With
the analysis of heat generation
and
radiation of the PEMFC engine,respective system
thermodynamics
system
mathematical model and
use
thermal
equilibrium model were established.Then by
of computer which is
simulation
software
Matlab/Simulink.the
simulation
