Abstract: The present invention is about a method of controlling weeds using the metabolites tenuazonic acid, iso-tenuazonic acid and their salts isolated from the cultures of Alternaria alternata (Fr.) Keissler. The spray of one of these compounds at the rate of 5 to 800 ?g/g can cause the main broad leaf, grassy and sedge weeds to hurt, wilt, even dry to death which exhibits herbicidal activity with broad spectrum, quick killing and efficient effect. The addition of adjuvants improves their herbicidal activity.

Humidifying methods include the following steps: cooling the hot and humid exhaust of the fuel cell to condense the water in the exhaust with the intake gas for the fuel cell; separating the water from the rest of the exhaust, and, delivering the water to the intake gas of the fuel cell. Humidifying devices include an outer shell containing a rotating inner shell. The inside of the inner shell forms a chamber where the exhaust is collected and cooled, and water is condensed and separated by the rotation of the inner shell. Openings on the inner shell allow the condensed water to pass through to one or more chambers containing the intake gas. The chambers are formed by the inside of the outer shell and the outside of the inner shell.
