Abstract
Intisari
Menyimpan hidrogen dalam bentuk padat sebagai paduan metal hidrid merupakan metoda baru untuk keperluan bahan bakar kendaraan transportasi karena memiliki densitas yang lebih besar. Sebuah tangki simpan hidrogen dengan volume sekitar 1 liter berisi serbuk nano partikel Mg2Ti5Fe6 sekitar 700 gram telah dirakit menjadi satu kesatuan dan diuji unjuk kerjanya serta dibandingkan dengan tangki kosong bervolume yang sama. Pengisian dan pengeluaran hidrogen ke dalam/luar tangki dilakukan pada suhu kamar dengan tekanan bervariasi 2, 6,5, dan 8 bar. Dari hasil percobaan diperoleh bahwa rasio kapasitas serapan hidrogen tangki berisi serbuk nano partikel Mg2Ti5Fe6 terhadap tangki kosong berturut-turut 1,3, 2,3, dan 2,8. Percobaan serapan hidrogen pada tekanan lebih tinggi tidak dapat dilakukan karena keterbatasan sarana, namun apabila tekanan dalam tangki diperbesar, maka kapasitas serapan hidrogen masih akan bertambah. Dari penelitian ini ditunjukkan bahwa percobaan awal penyimpanan-pengeluaran hidrogen padat dari tangki telah berhasil baik. Penelitian lanjutan dalam bentuk pemanfaatannya di fuel cell sedang direncanakan.

Abstract
Storing hydrogen in the form of metal-hydride is one of the most promising fuels for transport vehicles because of its high gravimetric density. A solid hydrogen storage tank with the volume of tank about one liter containing about 700 g of nano powders Mg2Ti5Fe6 alloy has been fabricated for performing the hydrogen charging-discharging cycles. Charging-discharging of hydrogen into/out from the tank is conducted at room temperature at the varied pressure of 2, 6.5 and 8 bars. It is exhibited that the ratio of hydrogen capacity of the tank containing Mg2Ti5Fe6 nano particle to the empty tank is 1.3, 2.3, and 2.8, respectively. Charging experiment at higher pressure could not be conducted due to the limit of facility. It is predicted that at higher pressure the hydrogen capacity of the tank will be increased. From the experimental results it is concluded that the preliminary study on charging-discharging solid state hydrogen has been done successfully. Further examination in the form of its application in the fuel cell is being scheduled.
