Abstract:
AlNi 또는 AlNi 및 AlNi결정상을포함하는니켈-알루미늄합금을저온에서제조하고리칭함으로써레이니니켈(Raney nickel)과같이표면에기공을가지는다공성합금을제조할수 있는다공성니켈-알루미늄합금분말, 이를이용한탄화수소개질또는수소발생촉매, 펠릿과같은성형체및 반응기, 이를저온으로제조할수 있는방법등이개시된다. 상기다공성니켈-알루미늄합금분말은 BET 표면적, 전체기공부피, 평균기공지름등에서우수한특성을나타내며, 촉매활성저하가없어메탄과같은탄화수소개질또는수소발생촉매로서유용하다. 또한, 상기방법에의하면다공성니켈-알루미늄합금분말을용이하고간단하게저온에서저가로대량제조할수 있다.
Abstract:
PURPOSE: A molten carbonate fuel cell is provided to enhance mechanical strength and to maintain stability by providing lithium source to electrode. CONSTITUTION: A molten carbonate fuel cell includes reinforced lithium aluminate matrix. Inside the one or more of an air electrode and a fuel electrode, lithium source is filled. The reinforced lithium aluminate matrix is reinforced by including aluminum particles. The melting point of the lithium source is 200-500 deg. Celsius. A manufacturing method of the molten carbonate fuel cell including the reinforced LiAlO2 matrix comprises the following step: providing the lithium source one or more frame channels among the air electrode and the fuel electrode.
