5W to <100W Fuel Cell Stacks

A single fuel cell consists of a membrane electrode assembly (MEA) and two flow-field plates delivering about 0.5 and 1V voltage (too low for most applications). Just like batteries, individual cells are stacked to achieve a higher voltage and power. This assembly of cells is called a fuel cell stack, or just a stack.

The power output of a given fuel cell stack will depend on its size. Increasing the number of cells in a stack increases the voltage, while increasing the surface area of the cells increases the current. A stack is finished with end plates and connections for ease of further use.

Below you will find many stacks that can easily be integrated into a system to provide an operational power system tailored for most specific applications. We even offer DIY and build it yourself fuel cell stacks and kits.
