Actions toward carbon-neutral society with fuel cell technology

Investigation of the Distribution of the Mass Transport and Reaction Rates in a Fuel Cell By the Integrated Fuel Cell System Simulator Including the Dynamics of Air, H2, and Cooling Systems

“…, 𝑇 CC,i , and 𝑇 CC, are given from the air, H2, and cooling system models (5) and C is given from the 1D (through-plane direction) FC stack model ( 4 𝑛̇a CH 𝑘 𝑘− , 𝑛̇a CH 𝑘 𝑘+ , 𝑛̇ CH 𝑘 𝑘− , and 𝑛̇ CH 𝑘 𝑘+ in Eq. [1] are expressed as follows by the Darcy-Weisbach equation ( 23 The detailed expression of Darcy-Weisbach equation is described with the gas states and the dimension of the channels as follows ( 23):…”

“…[4] to Eq. [1], the discretized expression of simultaneous differential equations about 𝑃 CH 𝑘 is derived for the momentum balance at each node of the anode and cathode channels. Non-linear terms in Eq.…”

“…Decarbonization are gathering attention in response of accelerating global warming in recent years and many countries have announced the declarations and policies toward it (1). Hydrogen is considered as one of the most promising alternative energy sources to the fossil fuel from the role of energy security as well as environmental viewpoints because of its portability and producibility from various renewable energy sources such as solar, wind, hydraulic, and geothermal energies.…”

“…A wide adoption of the FC system in a wide range of industries must be accommodated with the extension of the hydrogen fueling stations network unlike the conventional fossil fuel and electric power sources. The applications of the fuel cell system to a variety of purposes such as commercial vehicle, railway, construction, maritime, and aviation as well as passenger vehicle are investigated to promote H2 utilization in an entire industry (1). The fuel cell system manufacturers are demanded to develop a variety of products in parallel and in shorter development period.…”

Modeling of the dynamic behavior of an integrated fuel cell system including fuel cell stack, air system, hydrogen system, and cooling system

“…The worldwide investment to the business related with carbon neutrality and decarbonization has become active (1) especially after the Kyoto Protocol in 1997 (2) and the Paris Agreement in 2015 (3) for the prevention of global warming. Hydrogen (H2) energy is considered as one of the most promising alternative energy sources to the fossil fuels (4) from the viewpoints of storability, portability, and productivity from a variety of energy sources such as solar power and wind power.…”
