Description

Direct Methanol Fuel Cell (DMFC) Hardware applies liquid fuel to the fuel cell to generate power. DMFC involves gas evolution during the electrochemical reaction that greatly influences the performance of the fuel cell. Methanol has more energy in volume compared to hydrogen, and since it can be utilized in a non-compressed state, it has become a fuel of choice for several uses - including where size and weight are an issue as well as portability.

This DMFC fuel cell can be taken apart and rebuilt!

The DMFC hardware can also be used for Direct Ethanol Fuel Cell (DEFC) and Bio-fuel cell, in which liquid fuel is required to be managed to flow through the fuel cell.

This item includes all the key components to make such reactions occur. It also performs compression of the membrane electrode assembly (MEA) while providing uniform gas distribution and uniform temperature to the cell.

A nickel-plated plate serves as the current collector plate for the fuel cell. The nickel plating provides corrosion protection and good electrical contact with the graphite separator plate. A high-purity graphite plate with high electrical conductivity (900 Scm-1) and high thermal conductivity (117 Wm-1K-1) is designed with serpentine gas flow channels and manifold. A gasket is included to provide a secure seal for the MEA. High-power silicon rubber heaters are installed at both ends of the fuel cell to maintain a constant cell temperature.

Features:

  • Machined graphite separator plates with serpentine flow fields
  • Nickel-plated current collectors
  • Banana plugs for monitoring voltage
  • Belleville washer
  • Built-in silicon rubber heaters (40 watt) for maintaining cell temperature, with choice of voltages (110 or 220VAC)
  • Nylon fittings for gas tight connection to 1/4” tubing (for active area sizes of 5 and 25 cm²)
