How Many Cells do I Need in my Fuel Cell? (Simple Fuel Cell Design Guide)

As with Electrolyzers on my previous post, there are many nuances in the optimal design of a Fuel Cell.  The proper selection depends on the application, type of fuel cell, component selection and design (MEAs, flow fields, etc.) and a host of other factors. However, I will start with a simple tool that will help determine some general characteristics of a typical H2/Air fuel cell.  Thanks to our handy simple Fuel Cell Design Guide, you can take an IV curve of any MEA, choose an active … [Read more...]

How Much Hydrogen (or Oxygen) Will my Electrolyzer Make?

There are a lot of design considerations that go into an electrolyzer that will dictate what pressure they can operate at, their efficiency, safety, etc.  Today I will let you worry about all the mechanical design and talk a bit about the principles behind the electrolyzer and what this means to you (the designer).  Everything below applies primarily to PEM water electrolysis, but much of it may apply to other electrolyzer types as well.  If you want to skip the explanation, you … [Read more...]
