THE HYDROGEN TANKS All of our hydrogen tanks are produced in-house and specially designed for Mirai. 7 volts. Under the land of a Hydrogen fuel cell systems are of two fairly distinct classes, and each has different performance and long-term durability issues. Ballard offers a highly versatile, hydrogen-fueled, low power fuel cell stack prototype, the FCgen ® - micro. the stoichiometry must always be more than one: = n_ feed n_ consumed >1 [ ] = The reactant feed for H 2 and air into the fuel cell stack are now deﬁned by an anode and cathode stoichiometry : n_ H 2;feed = _n H 2 anode = IN 2F But there are other ways too. The stack is designed to contain enough cells to provide the necessary power for the automotive application. Fuel Cell Stacks “…using ElectroChem´s cells since 2009, when my group bought two 50 cm2 stacks for research activities…”, “We do really appreciate the robustness of the hardware…”, “We have assembled/disassembled the cells over a hundred times during the experimental research activities, always with excellent results in terms Save fuel cell stack to get e-mail alerts and updates on your eBay Feed. In the next section, we will look at the different types of fuel cells.
