The invention discloses a perovskite catalyst for methane and methanol reforming and the applications, belonging to the methane and methanol reforming catalyst field. The general formula of the catalyst combination is: A1-xA' xB1-yB' yO3; wherein, 0 is less than or equal to x is less than or equal to 1, 0 is less than or equal to y is less than or equal to 1, A or A' is La, Ce, Pr, Gd or Sm, B or B' is Cr, Zr, Zn, Ni, Co, Mn, Fe, Ru, Rh, Pt or Pd. The invention has the advantages of high activity and stability, good sulfur tolerant performance, high conversion rate and long service life, synchronously anti-seismic, small resistance and easy replacement and other excellences after being coated to the honeycomb structure. The invention adapts to providing hydrogen fuel and heat-electricity supply for fuel cell, reforming the hydrogen production of natural gas vapor in the distributed power generation technology or the hydrogen production of methanol spontaneous heating.
