Nickel Metal Anode Ink is an excellent contact paste for Solid Oxide Fuel Cell (SOFC) testing, and is especially good for enhancing the electrical contact on the anode side of a cell during fuel cell testing. The nickel ink can also be used as a reference electrode, but any electrical testing with the nickel paste will require that the sample be under a reducing gas to maintain good electrical conductivity.

Technical Specifications:

• Metal: Nickel (Ni)
• Quantity: 50 grams
• Solids Loading: 75 - 80% Nickel Metal by weight

Typical Use Guidelines:

• This is a great ink for making electrical connections for electrochemical testing of fuel cells, ceramic substrates, electrochemical materials, and metals. This ink can also be used to form the anode catalyst layers with proper modifications (such as after adding the YSZ in order to form ionic pathways within the anode catalyst structure, etc.).
• Stirring the ink before use is highly recommended. For best results, the ink should be stirred with a spatula or a glass rod to achieve an even consistency prior to use.
• This ink is typically fired at 1300 °C for 1 hour to ensure adhesion prior to testing at the desired test temperature (for making the catalyst layers with good bonding to the electrolyte).
• This ink is typically fired at 750°C or 850°C for 1 hour to ensure adhesion prior to testing at the desired test temperature (for making electrical connections to the current collector screens or current collector wires).
• This ink can be used for screen printing for generating electrical connections for wire attachments.

SOFC Tips for Making Electrical Connections:

Ensuring a solid connection between your electrodes and current collector is critical for obtaining good test results. Leveraging our experience in electrochemical testing, testing we have we offer the following suggestions for obtaining optimum results with our silver paste product.

Step 1:

Cut or punch out the metal mesh to the size/area that you want to test on your sample.

Step 2:

Cut the contact wire to the desired length, with a loop around the perimeter of the mesh with the wire extending past the sample. Place cut mesh in the center of your sample and the looped wire on top of wire mesh.

Step 3:

Apply the contact paste around the perimeter of the wire loop, apply a few drops across the mesh for best adhesion strength.

Step 4:

Cut and place a straight piece of wire next to the mesh on the sample. Again, cover with ink for adhesion. This will allow for 4 point conductivity testing and a lead for measuring voltage, while the other draws the current.

Step 5:

Dry in a 100°C oven for an hour or until the ink looks dry. Repeat all steps on the opposite of the sample in the same area.

Step 6:

Fire your sample to adhere your contact wires. Firing conditions: 1°C per minute to 800°C, hold for 1 hour, cool to room temperature sample in the same area.
