A (H) sensor composition includes a gas permeable matrix material intermixed and encapsulating at least one chemochromic pigment. The chemochromic pigment produces a detectable change in color of the overall sensor composition in the presence of Hgas. The matrix material provides high Hpermeability, which permits fast permeation of Hgas. In one embodiment, the chemochromic pigment comprises PdO/TiO. The sensor can be embodied as a two layer structure with the gas permeable matrix material intermixed with the chemochromic pigment in one layer and a second layer which provides a support or overcoat layer.

Gas permeable chemochromic compositions for hydrogen sensing

A chemochromic Hsensor includes supports including a plurality of metal oxide particles exclusive of titania, and a platinum group metal (PGM) compound on the supports. The PGM compound is an oxide, hydroxide hydrated oxide, PGM salt or a PGM complex. When the PGM compound is a PGM salt or a PGM complex, the supports can include titania particles.

Chemochromic hydrogen sensors

A method of generating hydrogen includes the steps of providing an amine borane (AB) complex, at least one hydrogen generation catalyst, and a solvent, and mixing these components. Hydrogen is generated. The hydrogen produced is high purity hydrogen suitable for PEM fuel cells. A hydrolytic in-situ hydrogen generator includes a first compartment that contains an amine borane (AB) complex, a second container including at least one hydrogen generation catalyst, wherein the first or second compartment includes water or other hydroxyl group containing solvent. A connecting network permits mixing contents in the first compartment with contents in the second compartment, wherein high purity hydrogen is generated upon mixing. At least one flow controller is provided for controlling a flow rate of the catalyst or AB complex.
