General grammar/syntax fixes in paper

E.g.,:

In addition to the decreasing fuel sources, also pollution and global ...
reaction between hydrogen-rich fuel source and oxygen
... of these devices owing to high efficiency relative
PEM fuel cells are a high-efficiency power source without pollution for urban vehicles, corroborated by recent legislative initiatives, That’s why these devices have become a great deal of attention to the option of fuel-cell-powered vehicles
Best fuel for fuel cell powered vehicle is hydrogen,
because the water is an only product of the reaction between hydrogen and air
protons that, flow via the membrane to the cathode
An external circuit that linked to the two electrodes containing the collection of electrons as electrical current
water and heat will be produced from the protons that flowing via the electrolyte membrane
The OPEM (software named based on open proton exchange membrane) written in Python, Python is a language that is very powerful for developers, but is also accessible to scientists.
In addition, dynamic models improve static models and complete the simulation process.
fluid science and material merge
make the simulation of fuel cell more
Simple linear regression used for this approximation and useful overall parameters such P(Thermal) and P(Elec) calculated by Simpson’s Rule
The method for using in this software is the specified inputs are presented according to the equations of each model by the user and outputs is in
That is represented by means of its voltage-current characteristic obtained in static operating mode
That the electrodes channel temperatures/pressures, t...

Also, watch out for arbitrary capitalization, e.g.,: hydrogen vs Hydrogen
