Fuel cell convert chemical to electric energy . Can anyone tell where is the mechanical part?
I would assume that would be the mech eng. part since mech eng. do take a course on material properties and fluid dynamics.
Engineering disciplines overlap. And all of them take the same classes in the first two years. calculus 1-4, chemistry 1-2 with labs, physics 1-2 including electricity and magnetism. All types of engineers can work in fuel cell development because all engineers have the similar knowledge from taking those core classes. As an Industrial Engineer, I have worked as a mechanical engineer, chemical engineer, environmental engineer, process engineer, manufacturing engineer, and I was offered a job to work as a civil engineer, but turned it down. My friend in mechanical engineering ended up getting his first job as a computer engineer. My friend in bio engineering also got her first job as a computer engineer. An engineer can work as any type of engineer, in any industry, with little to no training.
Someone has to design the package to put it in. The bells and whistles need design also. ie Bell box and whistle can.
