<p>PURPOSE: To improve the performance of a fuel cell by manufacturing a current collector the specific resistance of which is low in all directions. CONSTITUTION: Thermally expanding graphite powder is filled in a press jig, and successively pressed and compressed from three directions of X-axis, Y-axis and Z-axis. Consequently, each crystal of the thermally expanding graphite powder is oriented in a random direction such as vertical direction or horizontal direction, and the specific resistance of the resulting current collector is never enhanced in a specified direction.</p> |
