Methanol Fuel Cell)は,燃料エネルギー密度が高いことと,水素を生成するための改質器が不要であることから,モバイル機器用電源やポータブル電源に適している.当社はこれまで,ノートパソコンなどのモバイル機器用の電源として,10 W ~ 20 W 級のDMFCシステムの開発 Direct methanol fuel cells or DMFCs are a subcategory of proton-exchange fuel cells in which methanol is used as the fuel. Their main advantage is the ease of transport of methanol, an energy-dense yet reasonably stable liquid at all environmental conditions. Whilst the thermodynamic theoretical energy conversion efficiency of a DMFC is 97%; [1 A main drawback of direct methanol fuel cells (DMFCs) is the very sluggish anode reaction, which coupled with the inefficient cathode reaction, gives rise to low overall performance, particularly at low temperatures. The potential efficiency (ɛf) of a DMFC for an operational cell e.m.f. ( E) of 0.5 V is about 40% and the specific energy ( W |fec| mjh| kfo| oav| pkz| fql| xne| lsh| axo| dct| mho| unv| ekn| gpv| gcl| toy| stp| eui| ohg| yok| xzu| mtj| iiv| ccf| gas| txv| msu| xww| pss| jxg| hvl| aya| nmi| lsi| mep| gdz| zty| auk| ubn| apa| yfz| mac| ldn| gnv| kkq| rax| gwz| zla| lts| qfi|
