ABSTRACT

In marine environment it is required a fuel cell with low weight and low volume, fast response time (start up and shutdown), moderate work temperatures (60-70°) and good performance. As a Polymer Electrolyte Membrane Fuel Cells (PEMFC) do not present severe problems of corrosion because the electrolyte is a solid polymer and have a relatively long life and a high energy density, PEMFC is the option. Hydrogen is the fuel used.
