Electrically heated catalyst
The present invention is related to an electrically-heated catalyst in which cracks or ruptures of comb-shaped electrode portions are prevented by releasing thermal stress due to difference in thermal expansion between the carrier and the comb-shaped electrode portions. The catalyst includes a carri...

| description | The present invention is related to an electrically-heated catalyst in which cracks or ruptures of comb-shaped electrode portions are prevented by releasing thermal stress due to difference in thermal expansion between the carrier and the comb-shaped electrode portions. The catalyst includes a carrier; more than two comb-shaped electrode portions extending in a longitudinal direction; an electrically conductive underlying layer provided between the carrier and the comb-shaped electrode portions; and electrically conductive fixing layers bonding to the comb-shaped electrode portions and the underlying layer to fix the comb-shaped electrode portions to the carrier. The fixing layers are provided to be interspersed on the comb-shaped electrode portions and the underlying layer. Each of the comb-shaped electrode portions is fixed to the carrier by the fixing layers bonding to the comb-shaped electrode portion and the underlying layer locally at more than two points spaced apart. |
