ABSTRACT:
A washer fluid system provides washer fluid by blending concentrated washer fluid with waste water produced in the operation of a fuel cell. The concentrated washer fluid is stored in a replenishable container. A mixing pump automatically meters the appropriate ratio of concentrated washer fluid to water (i.e., 1:10), preferably by a dual chamber arrangement, wherein the waste water from the fuel cell and the concentrated washer fluid are drawn from their respective sources and mixed, creating a mixed washer fluid having the proper ratio of water to washer fluid concentrate. In a first embodiment, the system creates the mixed washer fluid in real-time on demand of the wiper system; in a second embodiment a storage reservoir holds mixed washer fluid for stand-by use of the wiper system.
