Abstract
A fuel cell includes a joint portion A in which a first conductive separator, an electrolyte-strengthening substrate and a second conductive separator are jointed in order with a brazing material. The electrolyte-strengthening substrate is formed so as to be larger than a joint area of the first conductive separator and a joint area of the second conductive separator in the joint portion. The electrolyte-strengthening substrate has an insulating property at least at an area where the electrolyte-strengthening substrate contacts with the brazing material.
Claims6
A fuel cell comprising
- a joint portion in which a first conductive separator, an electrolyte-strengthening substrate and a second conductive separator are jointed in order with a brazing material,
- wherein:
- the electrolyte-strengthening substrate is formed so as to be larger than a joint area of the first conductive separator and a joint area of the second conductive separator in the joint portion;
- and
- the electrolyte-strengthening substrate has an insulating property at least at an area where the electrolyte-strengthening substrate contacts with the brazing material;
- and
- the electrolyte-strengthening substrate has an end portion projecting toward outside by a given distance from an end of the first conductive separator and the second conductive separator.
A fuel cell comprising
- a joint portion in which a first conductive separator, an electrolyte-strengthening substrate and a second conductive separator are jointed in order with a conductive adhesive agent,
- wherein:
- the electrolyte-strengthening substrate is formed so as to be larger than a joint area of the first conductive separator and a joint area of the second conductive separator in the joint portion;
- and
- the electrolyte-strengthening substrate has an insulating property at least at an area where the electrolyte-strengthening substrate contacts with the conductive adhesive agent;
- and
- the electrolyte-strengthening substrate has an end portion projecting toward outside by a given distance from an end of the first conductive separator and the second conductive separator.
