This methodology allows the interconnecting models of the fuel cell voltage, power, and Relative Humidity (RH) as a function of operating variables such as current, pressure, temperature, the flow of hydrogen, oxygen, and water. The validation of the simulation results illustrates the influence of relative humidity on the fuel cell behavior. In addition, these variables are adjusted taking into account of relative humidity in order to reach a better performance of the system. For this reason, a control method based on inversion, namely the Maximum Control Structure (MCS) is used to make this energy source more accessible and to avoid the disadvantages of over flow and drying case in order to achieve a suitable relative humidity needed for the implementation of this fuel cell.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eAuthor:\u003c\/b\u003e Farid Saadaoui\u003cbr\u003e\u003cb\u003eISBN-10:\u003c\/b\u003e 6200049319\u003cbr\u003e\u003cb\u003eISBN-13:\u003c\/b\u003e 9786200049315\u003cbr\u003e\u003cb\u003ePublisher:\u003c\/b\u003e Noor Publishing\u003cbr\u003e\u003cb\u003eLanguage:\u003c\/b\u003e English\u003cbr\u003e\u003cb\u003ePublished:\u003c\/b\u003e 09\/03\/2025\u003cbr\u003e\u003cb\u003ePages:\u003c\/b\u003e 56\u003cbr\u003e\u003cb\u003eFormat:\u003c\/b\u003e Paperback\u003cbr\u003e\u003cb\u003eWeight:\u003c\/b\u003e 0.19lbs\u003cbr\u003e\u003cb\u003eSize:\u003c\/b\u003e 9.00h x 6.00w x 0.13d","brand":"Farid Saadaoui","offers":[{"title":"Paperback","offer_id":48154195853567,"sku":"9786200049315","price":29.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0662\/2982\/9887\/files\/img_040fe847-91a2-4c33-97bd-9ecd8989c50e.jpg?v=1770788537","url":"https:\/\/www.whiterainbookhouse.com\/products\/water-activity-control-of-pemfc-farid-saadaoui-9786200049315","provider":"WR Book House","version":"1.0","type":"link"}
