Fuel Cell Materials
The fuel cell electrode layer is made up of the catalyst and porous gas diffusion layer. When the fuel in the flow channels meets the electrode layer, it diffuses into the porous electrode. The reactant travels to the catalyst layer where it is broken into protons and electrons. The electrons move to the...
Low-temperature fuel cells have historically used CNC-machined graphite as bipolar plates. Graphite’s high-cost, high-permeability, and precise machining processes have presented difficulties for the large-scale market. Due to this, many other materials have been...
Selecting the appropriate technique to properly characterize the fuel cell is extremely important because it helps the user to understand why the fuel cell is performing well or poorly. These techniques will help discriminate between activation, ohmic and concentration losses, fuel crossover, and...
There are many novel hydrogen methods that are currently being investigated that offer the potential for higher energy density than conventional methods. These include hydrogen storage in carbon nanotubes. Carbon nanotubes are unique structures with exceptional electronic and...
Low-temperature fuel cells have historically used CNC-machined graphite as bipolar plates. Graphite’s high-cost, high-permeability, and precise machining processes have presented difficulties for the large-scale market. Due to this, many other materials have been investigated, including carbon composite materials and...
Most people wouldn’t think that much thought needs to be put into fuel cell components such as fuel cell gaskets, spacers, and end plates, however, every part of the fuel cell stack requires careful consideration. Incorrect fuel cell gaskets and end plates can lead to gas leaks and insufficient fuel cell stack...
In a previous blog post, we described bipolar plates and the associated materials for low-temperature fuel cells. The materials previously described are selected for fuel cell stacks at or slightly above room-temperature -- which means that the materials are chemically compatible with the stack between 0 – 140 °C. The fuel cells that operate at higher temperatures require...
In fuel cells, the flow field plates are designed to provide an adequate amount of the reactants (hydrogen and oxygen) to the gas diffusion layer (GDL) and catalyst surface while minimizing pressure drop. The most popular channel configurations for PEM fuel cells are serpentine, parallel, and...
Each component of the fuel cell must be designed properly – otherwise, you run the risk of decreasing fuel cell performance. The bipolar plates are termed “bipolar” because they have flow fields on both sides. This design is very convenient when you have membrane electrode assemblies (MEAs) on both sides. In a fuel cell with a...
The design elements of a micro or MEMs fuel cell stack are the same as a larger fuel cell stack, except that there should be special considerations for...
