Polymer Electrolyte  Fuel Cell
PEM, DMFC, DAFC, PAFC fuel cell  

​At Ecscell we provide fuel cell hardware for PEM hydrogen fuel cell, direct methanol fuel cell (DMFC) and phosphoric acid fuel cell (PAFC) applications.
A fuel cell is an electrochemical device that combines fuel (hydrogen or hydrogen source) with an oxidant (oxygen or air) to produce electrical power. The fuel cell is similar to a battery in that a fuel cell has two electrodes (a cathode and an anode) that are separated by an electrolyte.  The fuel cell can produce electricity as long as fuel and oxidant are supplied.
Picture
The bipolar plates, or separator plates, in the fuel cell serve the purpose of supplying fuel to the anode and oxidant to the cathode and also provide the electrical conduction between the cells. Thus, the bipolar plate should have very good electrical conductivity and very low gas permeability.

Membrane Electrode Assembly (MEA) is the heart of fuel cells.  The MEA has three basic components including the membrane, catalyst layer and gas diffusion layer (GDL).

A single fuel cell produces 0.6–0.8 V under load. To obtain higher voltages, several cells are connected in series to form a Fuel cell stack.

Ecscell cell hardware consists of high density graphite anode and cathode plates held between current collect plates and end plates.  The fuel cell has the advantage of a circular design, with bolts passing through the entire unit and using spring washers to provide uniform force across the assembly.
