Fumaric acid can form intermolecularhydrogen bonds (strong) while maleic acid forms intramolecular hydrogen bonds (weak), hence fumaric acid has higher boiling point than maleic acid.
Intramolecular hydrogen bonds do not have to be weak, but the strength of a hydrogen bond depends a lot on the O−H⋅⋅⋅⋅OO−H⋅⋅⋅⋅O angle. With intramolecular hydrogen bonds, it is often hard to achieve the perfect 180∘180∘ angle while the same is not a real exercise for intermolecular hydrogen bonds which have full degrees of freedom of movement on both sides.

Maleic acid or butenedioic acid is an organic compound that is a dicarboxylic acid, a molecule with two carboxyl groups. Its chemical formula is HO2CCH=CHCO2H. Maleic acid is the isomer of butenedioic acid, whereas fumaric acid is the trans-isomer. It is mainly used as a precursor to fumaric acid, and relative to its parent maleic anhydride, maleic acid has few applications.

When maleic acid loses hydrogen ion, then it forms a very strong intra-hydrogen bond so the acid is more stable and strong also. Also it contains two carboxyl groups on both sides so it is more stable while in fumaric acid, the carboxyl groups are at opposite ends.
