Muna 1966, General Electric Company yakagadzira mvura electrolytic cell yakavakirwa paproton conduction concept, ichishandisa polymer membrane se electrolyte. PEM masero akatengeswa neGeneral Electric muna 1978. Parizvino, kambani inogadzira masero mashoma ePEM, kunyanya nekuda kwekugadzirwa kwayo kwehydrogen, hupenyu hupfupi uye mari yakakwirira yekudyara. A PEM cell ine bipolar structure, uye magetsi ekubatanidza pakati pemasero anoitwa kuburikidza ne bipolar plates, iyo inobata basa rinokosha pakuburitsa magasi anogadzirwa. Iyo anode, cathode, uye membrane group inoumba membrane electrode assembly (MEA). Iyo electrode inowanzo umbwa nesimbi dzinokosha senge platinum kana iridium. Paanode, mvura inonatswa kuti ibudise okisijeni, maerekitironi nemapurotoni. Pakathodhi, iyo okisijeni, maerekitironi nemapurotoni anogadzirwa neanode anotenderera nemukati memembra kusvika kune cathode, kwaanoderedzwa kugadzira hydrogen gasi. Nheyo yePEM electrolyzer inoratidzwa mumufananidzo.
PEM electrolytic masero anowanzo shandiswa padiki-scale hydrogen kugadzirwa, ine yakanyanya hydrogen kugadzirwa inosvika 30Nm3/h uye kushandisa simba kwe174kW. Kuenzaniswa nealkaline cell, iyo chaiyo hydrogen kugadzirwa mwero wePEM sero inovhara iyo yese muganhu. Iyo PEM sero inogona kushanda paA yakakwirira ikozvino density kupfuura alkaline sero, kunyange kusvika 1.6A/cm2, uye electrolytic kunyatsoshanda i48% -65%. Nekuda kwekuti firimu repolymer harimirire kupisa kwepamusoro, tembiricha yesero re electrolytic kazhinji iri pasi pe80°C. Hoeller electrolyzer yakagadzira optimized cell surface tekinoroji kune madiki ePEM electrolyzer. Masero anogona kugadzirwa maererano nezvinodiwa, kuderedza kuwanda kwemasimbi anokosha uye kuwedzera kushanda nesimba. Mukana mukuru wePEM electrolyzer nderekuti kugadzirwa kwehaidhirojeni kunoshanduka zvakada kufanana nesimba rinopihwa, iro rinokodzera shanduko yehidrojeni inoda. Masero eHoeller anopindura ku0-100% shanduko yechiyero mumasekondi. Hoeller's patented tekinoroji iri kuita bvunzo dzekusimbisa, uye nzvimbo yekuyedza ichavakwa mukupera kwa2020.
Kuchena kwehydrogen inogadzirwa nePEM masero kunogona kusvika ku99.99%, iyo yakakwirira kudarika yealkaline masero. Pamusoro pezvo, iyo yakanyanya kuderera gasi permeability yepolymer membrane inoderedza njodzi yekugadzira misanganiswa inopfuta, ichibvumira iyo electrolyzer kuti ishande yakaderera zvakanyanya. Iyo conductivity yemvura inopihwa kune electrolyzer inofanira kunge isingasviki 1S/cm. Nekuti proton kutakura mhiri kwepolymer membrane inopindura nekukurumidza kukuchinja kwemagetsi, masero ePEM anogona kushanda nenzira dzakasiyana dzekupa magetsi. Kunyangwe sero rePEM rave kutengeswa, rine zvimwe zvisingabatsiri, kunyanya mutengo wekudyara uye kudhura kwakanyanya kwezvose zviri zviviri membrane uye yakakosha simbi yakavakirwa maelectrodes. Mukuwedzera, hupenyu hwebasa hwePEM masero hupfupi pane hwemasero e-alkaline. Mune ramangwana, kugona kwePEM cell kugadzira haidrojeni inoda kuvandudzwa zvakanyanya.
